Hi Loed,
The RSAX_* FMs are the right templates to use for creating a Datasource. The reason is that the Datasource expects a certain set of Importing, Exporting and Changing parameters in the FM. You can ensure that only by copying one of the RSAX* FM.
So to meet this requirement, please copy an RSAX* template and call the /POSDW/SEARCH_TLOG in the code
Regards,
Suhas
