How to Create a Custom Validation from Fiori App Manage Substitution and Validation Rules

As we are moving to Fiori first yet cloud ready approach for any development, why restrict us to GGB0 or GGB1 for creating validation or substitution rules?

We can utilize the Fiori application - Manage Substitution and Validation Rules to create the rules which will be applied to all the standard processes such as standard interfaces, GUI T-codes and managing standard processes in custom program.

In this blog, we will create a custom-defined function in the validation rule on asset creation or modification done through the Fiori app - ‘Manage Fixed Assets’. The rule will validate against the supplier assigned to the asset master record.

RDG eases the process of data replication through SOA services with custom enhancements.

Syniti RDG is an SAP-endorsed application on the Business Technology Platform (SAP BTP) to facilitate MDG implementation with intuitive UI and process automation.

RDG eases the process of data replication by setting data replication configuration steps like data replication model, create and maintain business systems and can map standard and customized attributes with different mapping transformations. This simplifies the process onto one easy to navigate screen. RDG replication via IDoc or via services (WSDL and SOA) are available and are dependent on the outbound implementation selected. Custom enhancements with replication of data can also be created in SOA proxy structure depending on business requirements.

BODS migration

In this blog, I have detailed the steps taken for SAP BODS application migration from existing on premises to HANA database including the DR Testing Setup.

The Purpose of this blog is to provide a guidance path for migration of the BODS Application to HANA.

Existing Landscape Design:

1. The IPS and DS version remain the same as on premises.

SAP BTP, ABAP in the Cloud Custom Code Transformation using abapGit and gCTS

abapGit and gCTS (Git-enabled Change and Transport System)

◉ The basic idea behind abapGit is to exchange source code between any ABAP systems using a Gitbased repository.

How to improve the ADT Class Runner with additional Features

What is a Class Runner?

A class runner is a great tool to test code snippets and run code directly from ADT. You can even write a simple log to the console in Eclipse.

What can be improved?

When using multiple systems and complex projects I got annoyed at some point in time, that I don't know from which system the last log was, when it was written by which runner and if the last execution has finished or failed maybe.

Usage of Custom Destination Service in BTP, ABAP Environment

The regular Way

In BTP you configure the destination on subaccount level, here you see how to do so:

How to develop Customer creation Application in SAP Build Apps with OData service

Implementing SAP OData URI to SAP Build and Creating Customers in SAP BUILD which can replicate to SAP System

Business Scenario: -

How to create Customers using SAP Build Apps and OData Service.

Prerequisites: -

-> You Have an SAP BTP account or trial account.

Declaring Dynamic UI5 Fields in SAP Build Process Automation

While automating SAP Fiori applications, one might come across some dynamic UI5 elements such as mentioned in the snapshot below.

In most cases, recorder may not be able to uniquely identify the elements, thus terminating the automation where it may not find the suitable elements.

SAP BTP ABAP Environment – Pre-Upgrade Option for Release 2402

Overview

Providing a significant number of new features is an important goal of release upgrades to deliver innovations to our customers and partners.

An upgrade is intended as a “no event” for customers and partners. For example, only compatible changes of released objects (APIs) will be delivered. But we recommend performing a test of the custom-built productive apps in a test environment for the new release. The complexity of the technical dependencies between the custom-built apps and the underlying environment cannot be tested isolated, only including the ABAP environment on SAP side. Therefore, we offer you to upgrade selected systems 15 days in advance to test the applications prior to the planned standard-upgrade.

Alternative option for IMPORT/ EXPORT using Shared Memory SHMA approach.

Motivation:-

In this blog you will learn how to use shared memory as alternative option of ABAP Memory(Import/Export).

Business Scenario:- Many of times we need Import & Export at the time of SAP Enhancement or other requirements so Here use of shared memory which is also alternate option of Import/ Export and as per SAP standard guideline this approach is highly recommended.

SAP ABAP RAP: Custom Entities with compositions relationship in a Fiori Elements App

Introduction:

ABAP Restful Application Programming is an efficient and cloud-compatible development model that enables rapid creation of Fiori apps.

This programming model facilitates both Managed and Unmanaged Implementation approaches, although the core data source must originate from a CDS view or a table within the same system in both scenarios. However, the non-key fields can be calculated on the fly using virtual elements.

When retrieving data from a remote source through an API or performing complex calculations, managing CDS view entities becomes challenging. Further complexities arise when compositions  are involved.

Monitoring the Performance of Outbound Communication in the ABAP Environment in the Cloud

Since the ABAP environment in SAP BTP typically interacts with other BTP services, you may be interested in a performance monitoring of such outbound communication. In this blog post, I’ll show you how you can use the System Outbound Communication app in the ABAP environment. You can even get alerted by mail if the performance of a specific outbound service gets critical. In the example I’m describing here, I am logged on to an ABAP test system in the cloud in the role of a customer (with the administrator role).

Communication Scenarios

When you open the app, you first get an overview of the top 10 outbound communication scenarios by calling time of the past day. If there are multiple communication arrangements that belong to one scenario, they are aggregated to one column in the chart.

Analyzing performance degradations in the ABAP environment in the Cloud

As an administrator or developer, you need to keep track of the performance of your own applications in the ABAP environment of SAP BTP. Ideally, you have an app that not only shows you when performance deteriorates, but that also allows you to drill down to the relevant requests and the associated code.

In this blog post, I would like to show you a real-life example of how you can use the System Workload app to analyze a performance degradation. The following scenario was captured during a normal performance regression review of a change in the SQL statement processing for one of my development projects. I had changed a sequence of SQL statements and later checked its impact on performance using this app.

ABAP RAP: Side Effects in CDS Behavior Definition and its variants

Introduction

 

​The most awaited feature was released for SAP BTP – ABAP Environment in 2302. It is none other than ‘Side effects in CDS Behavior Definition’.

I have been waiting for this feature and can’t stop myself from trying it. I thought the syntax would be complicated and was surprised when I realized they were so simple and readable.

​​​Side effects are useful in UI scenarios based on draft-enabled BOs to notify a Fiori Elements UI that data changes of defined fields require the recalculation of other data values, permissions or messages.​

Alternative to BDC for Transactions F-30 or FB05 in RAP/Fiori Apps for Posting with Clearing

Posting the documents with Clearing open items and doing the transfer postings is a very common requirements in most of the SAP implementation FICO based projects.

Clearing can done in multiple ways

◉ G/L posting with clearing

◉ Customer – Customer  Posting with clearing

◉ Vendor- vendor Posting with Clearing

How to use Side Effects in ABAP RAP (Restful Application Programming) Model

In this beginner blog post we are going to see how we can use Side Effects in ABAP Restful Application Programming Model.

What is Side Effects:

When user makes a change to a field on UI, and this change effect the content of other field, this behavior is called Side Effect.

Annotation to Implement Side Effects:

Some more annotation properties are available but for this demo we are only using below 2 Annotations properties.
