The main aspect of an ERP systems are:

◉ Business Processes

◉ Extensibility

◉ Data

◉ Integration

◉ Operations

Creating ABAP Dataframes for SAP PAL

Machine learning algorithms often need large datasets for training. E.g. the MNIST dataset consists of 100.000 records. Each record represents a little greyscale image of size 28x28 pixels of a handwritten number and the respective number as integer value ,  i.e. 28x28 =  784 integer values in the range interval [0,255] and one integer value for the number value.

Assume you want to train a neural network in PAL using AMDP (ABAP managed database procedures) in order to predict the number. For this task you could e.g. use the PAL algorithm "Multilayer Perceptron", which is a neural network. In order to supply the input neurons with data a dataframe is needed, i.e. an ABAP-DDIC structure containing the following fields:

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:

Upload Excel using SAP RAP Only

Develop an SAP RAP based App to upload excel (CSV) file just like you used to develop SE38 classical report.

We often get this requirement of developing a utility to create/update mass data for a BO such as Purchase Orders, Materials, Sales Orders etc. In S/4 HANA, the customer prefers to use SAP Fiori applications, rather than using the old classical reports. But can we develop a Fiori application to upload a file without involving using SAP UI5? Yes, we can.

Dynamic Derivations using BADI in SAP MDG

Business rules are one of the important feature in Master Data Governance Process. Deriving the value for particular field of an entity can be done either by BRF Plus or BADI. This Blog Post explains you about creating complex or dynamic derivation rules which can be achieved through BADI.

In this post, I am taking the example of deriving Cost Centre value from Cost Centre Entity of Finance Data Model. Its a kind of Mandatory and derivation rule and the naming convention should be followed.

Unable to log in to SAP BusinessObjects CMC

We were recently performing regular maintenance, including an OS patching of the SAP BO development server for one of the SoftwareONE customers.

During the patching, some issues were encountered leading to a failure. It was decided to restore the operationability of the application by reverting to the previously backed-up state of the VM back to the patching event, and the Basis team was tasked to bring the application up and do the sanity tests.

The application was able to start but the login to the CMC was denied.
