How can I see all the Transaction Code that the client is using?
How can I see all the List of Transaction Code that the client is using?
Did you mean to ask
transaction types the client is using?
If so, go to SPRO (in ERP system) and follow this path:
Sales and Distribution --> Sales --> Sales Documents --> Sales Document Header --> Define Sales Document Types
All the transaction types that are not used have an X in the column Block.
