ABAP Tutorials, Guides, Training, Manuals
The code book contain the beginners level programs for new ABAPers. The book covers almost every basic aspect that a programer in this domain should know.
Often it is difficult to say, which Authority Objects are needed for certain processes in SAP. To avoid too many authorities for technical users in a productive system, the following steps should help to assign only the authority objects that are really needed for transaction exection:
Note! The steps described below should only be done together with you System Administrator.
We need RFC destination to connect either to non-SAP or SAP data externally from our existing system. To make other systems available for the access, we need to provide an RFC destination in our SAP such that it accesses the external system.
To summarise you can communicate via RFC:
1. R/3 -> R/3
2. legacy -> R/3
3. R/3 -> legacy
BAPI is a useful resource provided by SAP though which we can communicate with SAP also from external envirnment / sources. The following code shows the example of how to call BAPI externally, although SAP authentication for the user is done.
The example is a program developed in Visual Basic which I developed in my learning phase. It gives an idea about the hierarchy that needs to be followed when calling BAPI.
The example consists of three BAPI calls namely, for PO, GRN and Sales Order creation. The code is also available for download, but may require a bit tweaking.
There are requirements for an ABAP-HR programmer for creating custom HR infotypes.
The following PDF shows a walk-through of the steps required to set up custom Infotype from scratch.
The steps include creating new Infotype from PM01, to defining structure for it, to defining attributes, till dialog module assignment.
