I tried to use this function to check the integrity of master data in the start routine of transfer rules. My purpose is to fill a specific table with errors, according to my own rules (and not standard ones).
The problem is that the loading process is stopped by RSAU_READ_MASTER_DATA with the first error it finds. And a message says "the value xxxx doen't exist in master data".
Do you know how to use the function with no message display ?
