When loading a Master data from ERP system, this error occurs:
Data structures were changed. Start transaction beforehand
Message No. RSDS129
The generated data structure and the generated access program were changed since they were last used. Only the old references are stored in the program buffer.
You can only use the generated code (and the preview function) when the transaction is restarted. When you restart the transaction, current sources are loaded.
Restart the transaction. (DOESN'T HELP AT ALL...)
