Extending Fiori Apps in S/4HANA using the Adaption Transport Organizer

During one of my recent S/4HANA implementations I had to extend a standard SAP Fiori App (Manage Supplier Quotations) with an additional input field. Never ever had I thought this could be so easy!

During this blog I’ll walk you through:

◈ Setting up the Adaption Transport Organizer (ATO)
◈ Extending a standard Fiori App (Manage Supplier Quotations)

Locking the GUI apps from the Fiori/UI5 has never been so easier (via the Durable Locks for ABAP programming model for Fiori)

This blog is about understanding how the durable locks works in the new ABAP programming model for Fiori in creating the pessimistic locking for the Fiori apps which will also lock the GUI application.

I’ve seen people (including myself) struggling to answer the customers when they talk about pessimistic locking in Fiori apps as SAP officially given only ETAG functionality is optimistic based locking. But not anymore thanks to the durable locks which will create pessimistic locking for Fiori and GUI apps together at a time.

How To Use eCATT Script via HTTP Request

eCATT is a very powerful tool for test automation in the context of SAP. In this blog I describe how to call eCATT scripts via HTTP request. This approach is very similar to another with PowerShell, which I described in another blog. The difference is here that you don’t need an additional library and therewith is it possible to call eCATT scripts nearly from every tool.

Creating Custom Output Type for Sales Scheduling Agreement in BRF+

Introduction

Business Rules Framework Plus (BRF+) is a Business rules System which is developed in ABAP by SAP. It is a part of SAP NetWeaver 7.0 EHP2 and hence requires no additional SAP License. It provides seamless user experience with features like simulation, transport, XML export or import.

Tip: How to use Memory Mapped Files with ABAP/eCATT

During my tests with the RPA tool UiPath Studio in conjunction with eCATT it seemed necessary for me to think about an effective way of exchanging data. One of the standard options of interprocess communication (IPC) in Windows environments are Memory Mapped Files (MMF). So I decided to check if it is possible to use them in this context. Here is now the second step where I describe how to use the same approach in eCATT or ABAP.

Add fields to ALV in FINT

Introduction

I have shown how email sending with Smartforms can be archived. This feature is not the only enhancement that can be applied to FINT.

In this blog I will show how ALV of FINT can be enhanced by new fields that will ease the work with interest processing.

Expose CDS Views as OData Service

There are 3 different ways you can expose CDS views as OData service:

1. Import DDIC structure using SEGW Netweaver Gateway service builder transaction.
2. Reference Data Source using SEGW Netweaver Gateway service builder transaction.
3. Using Generic Annotations. (@Odata.publish:true)

Create an Excel worksheet (XLS file) using structures of the data dictionary

This blog demonstrates how to create an Excel worksheet based on structures of the data dictionary dynamically. The development consists in create an Extensible Markup Language (XML) file using Document Object Model (DOM) API that can be read on Excel program.

ABAP Programming Model for SAP Fiori (Draft based) for NON GUID Keys & Much more..

Introduction:

From Help:

The ABAP programming model for SAP Fiori defines the architecture for efficient end-to-end development of intrinsically SAP HANA-optimized Fiori apps in SAP S/4HANA. It supports the development of all types of Fiori applications like transactional, search, analytics and planning apps and is based on customer-proven technologies and frameworks such as Core Data Services (CDS) for defining semantically rich data models, OData protocol, ABAP-based application services for custom logic and SAPUI5-based user interface.

ABAP on SAP Cloud Platform – ABAP Restful Programming Model

In this blog I am going to explain steps to develop Odata service based on ABAP on SAP Cloud Platform architecture using ABAP Core Data Service (CDS) views. The architecture overview is as follows:

How to save import parameter values to RFM from external system

Introduction:

The intent of this blog is to show how to save the values being imported to parameters of a remote-enabled function module (RFM) as Test Data when it is called by an external system. Saved data can then be retrieved via the “Test Data Directory” screen of the function module. Note that this could also be done for a function module that is being called internally; however, this blog will outline an example of data coming from WebMethods to BAPI_PO_CREATE1 in an S/4 system.

BTE 00001110 – CHANGE DOCUMENT: Save the standard data VS FI Validation Rule

I would like to share with you the use of Business Transaction Event 1110 – CHANGE DOCUMENT: Save the standard data comparing to the FI Validation Rule.

Many experts in SAP don´t know about the BTE’s and mainly the BTE 1110 – CHANGE DOCUMENT: Save the standard data.

How to trigger custom message in F110

This blog is to demonstrate the example on how to trigger custom error message in F110 and do not proceed for payment due to the error.

Introduction

There is a requirement that the payment run process should not happen when there is custom error. Here, this blog will cover the error that ‘ if the vendor email is not maintained’ then the F110 payment run will not proceed and will show the error.

Steps for migrating file interfaces to different codepage

I will be discussing some of the steps needed for adjusting file interfaces when we migrate system to a different code page.

In our organization we faced challenges with file interfaces when we migrated ERP from AIX to Linux OS and  to Unicode system (code page of the system from ISO-8859-1 to UTF16-LE and the endianness changed from Big Endian to Little Endian).
