I am using LSMW and trying to post the document through direct Input program RFBIBL00. I want tax to be calculated automatically, so I set BBKPF-XMWST = 'X' and tried to post. But system (S/4 Hana 1610) gives me error "Calculate tax" option not possible. See below details of the error.
Message no. RW308
You called up the fast FI data interface with the option "Calculate tax".
This functionality is not defined in the fast FI data interface.
The standard batch input procedure automatically includes the document in a session which then posts it.
When I try to process the session generated in SM35 manually, document get posted correctly with tax calculated. Only getting issue in direct input. Please let me know what is possible solution.
