How To Create SAP ABAP HR Reports Using A Logical Database (LDB)
SAP HR Logical Database (LDB for short)
A LDB provides read-only access on a group of related database tables to ABAP programs. There are various advantages of creating HR Reports using LDB such as the automatic use of Central Authorizations, High performance, In-built validation to check user input and Meaningful data access through standard selection-screen .
There are four LDBs available in HR ABAP:
| LDB | Used for |
| PNP | HR-Administration, Time Management, Payroll |
| PNPCE | HR-Administration, Time Management, Payroll with concurrent employment functions |
| PCH | Personnel Development, Organizational Management, Training and Event Management |
| PAP | Recruitment: |
In this tutorial we will create a report using the LDB PNPCE and I strongly suggest you to use PNPCE over PNP in all your new developments because it includes all the functions of the PNP logical database and offers additional evaluation options. Also it provides us an improved selection screen and your report benefits from this even if your programs do not use the functions for evaluating Concurrent Employment.
