Call logical database from a FM

Hello gurus,

I have a report with ldb PNP. In the report a have this tables:

TABLES: pcl1, pcl2, pc2b0, pernr, rpfausg.

This are giving me access to tables like: psp, fehler, pt, zes.

Now I'm trying to get the same structures/ tables from a FM. As I cannot use the ldb here an need to get this information calling a FM.

Does anyone did this? Do you know the FM that I need to use and can you give me a code example?

Kind Regards,

Ionut
