SAP Cloud Transport Management

Introduction


I have experimented a bit with SAP Cloud Transport Management.

The Big Picture


As usual on SAP BTP you have to use a service from the service marketplace to use the SAP Cloud Transport Management. You also have to create a solution landscape on the SAP BTP. 

I designed it as follows:

MFS Testing strategy for smooth transition and reliable performance

It is crucial to test the MFS solution thoroughly before Go Live to ensure a smooth transition and reliable performance. Different projects require different test strategies. Below, I share some general approaches I followed in various MFS implementation projects.

During the build phase, we usually use an ABAP program (SCWM/MFS_TEST_MFS_RECEIVE2 or a custom program) to test our solution. However, this does not provide visibility into how the PLC would react to different situations. Therefore, we use emulation software where the warehouse automation layout is modelled and all possible logic is implemented. In SIT, we typically use this emulation software to test the MFS solution.

MFS Testing strategy for smooth transition and reliable performance

Many cases, existing PLC logic is changed to ensure it can work with MFS solution. Even sometimes a master PLC is introduced which communicate with lower-level PLC or hardware’s & then communicate with MFS with telegram messages. So, it is important to test these PLC changes. For this we usually place the new version of PLC software in place of the existing Legacy PLC & do the test with MFS. These kind of test needs warehouse down time.

Many warehouses run 24/7 & getting a down time is a big challenge. So, it is very crucial to plan these kinds of tests in detail so we can utilize this downtime to the fullest. This is also a great opportunity to test all your warehouse automation & integration with other software’s.

We usually try to replicate a day after Go Live in the testing environment which gives us a very good visibility & confidence how the EWM/MFS solution would work in production environment.

MFS Testing strategy for smooth transition and reliable performance

Operational test Planning:

We need to ensure following key items are addressed before we start operational testing for Warehouse Automation with MFS.

Master data: Need to ensure all the master data such as products, packaging specifications, any other data entries are in place in test system so you can use these production data for these tests. These test data also need to be available in other software test system. You may need to block bins not part of the agreed test scope so to ensure testing process does not mess up current legacy production inventory.

Network issues: Network team need to set up the firewall rules so Test MFS system can communicate with Test PLC without any issues. Similarly, connection between Test EWM/MFS system, Test Fleet management software which controls the AGV & any other application which we would like to test as part of end to end operational test needs to be in place.

Resources: It is crucial to have resources from business teams and all other applications available during planning & execution of operational test. All warehouse key resources should be trained on the new MFS processes so they can participate actively and appreciate the test results..

Test Scenarios: You need to have test cases covering both happy paths and all exception scenarios. Decide how to recreate exception scenarios. For example, to simulate a "No Read" scenario from a scanner, you might need to cover the scanners so the PLC sends telegrams accordingly.

Test Cases/Pallets: Ensure you have enough cases and pallets with all possible data variations. For partial pallet scenarios, have partial pallets ready. Also, include oversize pallets, mixed pallets, etc. Decide the entry and exit points of these pallets, Cases for each test. For instance, in the Goods Receipt process, determine where pallets should enter and where they should be stored. If cases are used to build pallets, decide where cases need to enter the system and where pallets should come out.

Rollback Approach: It is critical to have a solid roll back plan so after the test everything is brought back to BAU status. 

Operational Test Execution:

During the test, all the test results, observations need to recorded correctly. Not everything goes as planned, so need to be able to change the approach on the fly with due consideration to overall design architecture.

After Test execution:

During the test, things move very fast & so many transaction data gets posted. So after the completion of the test, it is important to analyze the data to see of anything has any abnormal posting. Log all defects & track for its closure.

It is very critical to complete the rollback steps before handing over to business. Such as replacing the test PLC with current production PLC, changing the IP address at MFS. Network team reverting the Firewall rules. If any test EWM labels are used, it is necessary to replace with actual labels. If any BAU labels are damaged, ensure to reprint them in current legacy software. Do a stock count & ensure they are in right places. Sometimes you need to bring back the pallets, cases to its original positions or manually adjust the new position of these stock in legacy WMS application.

Next time "Just Ask": Simplifying Data Exploration - Configuration using a standard ABAP CDS View

Introduction


Just Ask is a feature in SAP Analytics Cloud which is powered by Generative AI and allows users to ask questions in natural language and receive visualizations and insights based on the data available in SAP Analytics Cloud.

This feature uses machine learning and natural language processing to understand and interpret user questions and provide relevant data visualizations and insights. This allows users to easily access and interact with data without needing to have expertise in data analysis or querying languages.

Availability and Roadmap


Just Ask -initial release is available from QRC Q1 2024 in all SAP Analytics Cloud (SAC) tenants hosted on Cloud Foundry (AWS), Google Cloud Platform, and Microsoft Azure. It is not available for tenants hosted on Neo or AliCloud environments.

Currently, Just Ask works with data from acquired models and Live SAP Datasphere models and supports English language.

Just Ask vs Search to Insight - Is it just rebranding?


Some frequently asked questions that I have observed. The 'Just Ask' feature resembles the 'Search to Insight' feature, what sets them apart? Is it merely a rebranding of the same feature?

Short Answer - No, they are not same.

Detailed Answer - Even though Search to Insight and Just Ask address the same audience and process natural language queries to present data in graphs/charts the difference lies in the core NLQ technology used in Just Ask. Just Ask leverages AI models to provide more relevant results. Another big difference that I see is in the control and refinement options that Just Ask provides to the admins which is not there in Search to Insight. Details below:

Some features that set Just Ask apart from Search to Insight and are not available in the latter:

  • Central place to define models to be enabled as searchable - this reduces ambiguity (say models with same name) and also if the models are not fully ready or partially released or may not have refine data.
  • Define synonyms and rules to refine results - example if the typed question by user includes "by year" or say "current month" then admin can define a rule to restrict data to the "current year", "current month" etc. depending on the model in question and business requirements.
  • Create questions (search queries) presented as recommendations to end users
  • Based on AI models (LLM) and use embeddings

In Search to Insight by default all the models were included, no option in Search to Insight to configure/refine models/result by leveraging synonyms/rules/questions.

Enabling Just Ask


SAP Analytics Cloud tenant admin can enable the feature from the below path and can be easily accessed from the top toolbar icon

Consuming S/4HANA ABAP CDS View in SAP Analytics Cloud


Now to understand how to configure a model for Just Ask, I have used a standard ABAP CDS View to create a model in SAC and enable it for Just Ask.

The standard ABAP CDS View I am using is Material Stock for Key Date (C_MaterialStockByKeyDate).

Structure of SAC model on top of ABAP CDS View:

Note: Please refer SAP help on SAP Analytics Cloud on how to import ABAP CDS views from S/4HANA to SAP Analytics Cloud or many great blogs already written on this topic.

Launching Just Ask


Click the Idea /Bulb button from the toolbar (refer Figure1 above).

Customizing Just Ask:

On the Just Ask screen admins can add free text using "edit description" to maintain description about Just Ask or general information for the end users.

Example - I have maintained to share what models have been indexed or available. Another example - One can maintain models from a particular project or business area which are available for Just Ask.

There are two options available:

Option 1--> Add the model directly to the current session OR

Option 2--> Index the model using Manage Models option (top right) to make it available for the users

Note: In above screenshot - Material Stock is not indexed yet and that is why it is not in the list of indexed models.

Option 1 --> Add Model directly to Just Ask for the current session - The model added, will not be available after the end of current session.

Defining Rules: Simply put rules are like logic which gets executed when certain conditions are met.

Example - If the prompt has Stock Quantity then show results with Plant , Base UOM and Stock for 01.01.2024 to 11.06.2024 and for only US Plant.

Note: It is always recommended to test the rule and make adjustments to get desired output before publishing it.

Sample Questions:

Just Ask also provides a great feature to create "Sample Questions" for a model. This feature allows admins to create sample questions (queries), helping users explore available data and fields easily. It's a quick start to get users comfortable with the data in the model and boost adoption. This is another way to customize Just Ask for the end users.

Creating Sample Questions:

Indexed Model related setting:

An indexed model can be disabled as searchable for Just Ask. Some examples when this option can be used:

  • Model is indexed however, configuration (synonyms /rules etc.) is still work in progress OR
  • Model is no longer required OR
  • Is not fully ready yet

Next time "Just Ask": Simplifying Data Exploration - Configuration using a standard ABAP CDS View
Figure 20

Just Ask in Action

Now as the model is now indexed and configured by defining synonyms and rules, let's see Just Ask in action. The Material Stock model is now available under indexed models.

Case 1: Here Inventory and Production Facility both are synonyms and as per the rule defined results are filtered out to show only US Plant and between January 2024 to June 2024

Next time "Just Ask": Simplifying Data Exploration - Configuration using a standard ABAP CDS View
Figure 21

Case 2: For this case rule was disabled. In this case Quantity, Location, US are all Synonyms defined in the model configuration, where Quantity --> Stock Quantity, Location--> Storage Location and US --> Plant 1 US

Next time "Just Ask": Simplifying Data Exploration - Configuration using a standard ABAP CDS View
Figure 22

Case 3: Searching by synonyms defined for the data values. Here synonym "Cake" was created for Materials filtered in the query generated.

Conclusion

In conclusion, Just Ask offers advanced NLQ technology and greater control for administrators compared to Search to Insight. These features reduce ambiguity and improve relevance while providing more customization and flexibility in presenting data to end users, making Just Ask a more powerful tool for natural language query processing.

Introducing new type of Data Access Control "Operator and Value" for SAP Datasphere

Row-level security in SAP Datasphere is implemented via Data Access Controls (DACs) to allow a more granular assignment of authorisations and access to data on dedicated views within a Space.

In general DACs are objects which can be created in SAP Datasphere as objects in their own right which control access to data for each user within a Space. Hence, an integral part of a DAC is a list of values a user is allowed to see for a dimension (e.g. 'Sales Units') a user is allowed to see. This list can be maintained  in a local table, a view or even a table function. Each value a user is allowed to see must be represented by one record in this list of authorised values.

CDS based Analytical oData for Fiori

During my developments I found that analytical oData services (or maybe to be more precise "analytical entitysets" within oData services) are needed quite often but it's not very well documented what options can be used to create them. In most of the official literature you will find oData generated on top of "analytical query" but this option is not supported in Restful ABAP programming model and makes some stuff (like adding additional entitysets in the same service) difficult.

As a first thing let's explain "analytical oData" on a very simple example and probably most common scenario: you have some kind of document item which has for example Supplier, Company Code, Fiscal Year, Amount with Currency code and Quantity with Unit. And you perhaps need to get the "sums" of amounts and quantities on different levels

Extract blob data (PDF) from CAPM using python library of Document information extraction service

Introduction:


Document Information Extraction helps you to process large amounts of business documents that have content in headers and tables. You can use the extracted information, for example, to automatically process payables, invoices, or payment notes while making sure that invoices and payables match. After you upload a document file to the service, it returns the extraction results from header fields and line items. 

Use case:


1. Extract the documents (invoice detail) from an application where it is maintained as an attachment, and it is stored as a blob object in HANA database tables. 
2. Before the data is imported into a HANA database, transform the information that was retrieved from the blob object into a format that can be utilized for further analysis.

SAP Fiori tools May 2024 release adds closer integration with ABAP Development Tools

SAP Fiori tools May 2024 release adds closer integration with ABAP Development Tools 


With the 2405 client release of ABAP Development Tools (ADT), combined with the latest SAP Fiori tools release, users can now have a more integrated experience when working between ADT at the backend and SAP Fiori tools for front-end development. No longer does the developer need to manually switch between the tooling environments and remember which system and entity they wish to use. Instead, with one button click in ADT, users can seamlessly switch from ABAP to SAP Fiori development. 

As mentioned in our SAP Fiori tools March update, SAP Fiori tools now enables users to launch the Application Generator directly from ADT and skip having to select a data source and entity in the generator if they already have the SAP system and entity chosen in ADT. With the 2405 client release of ADT, the development work has been completed and the feature is available to our cloud customers.
