Hello,
I need to make one field mandatory in LT42 screen. I wanted to know whether field selection can be controlled somehow via warehouse management IMG configuration.
Or I know of tcode SFAC and SFAW to control parameters.
Please suggest.
Thanks
Madhura
Hello there,
There is no such functionality for mandatory field selection in WM compared to MM. However I do suggest that you look into enhancement MWMTO001 (Enhancements for end of transfer order generation) to meet your needs.
With this user exit, you can update your own data at the end of the
transfer order creation.
Call transaction and other important requirements
The user exit is performed at the end of function module
L_TA_HINZUFUEGEN in SAPLL03T. This means that the source code can run
both asynchronously in the update program and online. For this reason,
all error messages must be issued as abend messages to guarantee correct
termination with rollback. Furthermore, you must not use any key words
such as COMMIT WORK, ROLLBACK WORK, LEAVE, etc. (neither directly nor
indirectly when calling other function modules). Therefore, you must
never start transfer order creation via a function module. If the call
is performed asynchronously, you cannot access data of other user exits
from TO processing in online mode.
Parameters and options
The user exit in the program is function module EXIT_SAPLL03T_001. In
order to be able to use the user exit, you must create Include ZXLTOU01
and activate the enhancement with transaction CMOD. As parameters, you
can use the TO header (import parameter I_LTAK_VB) and the items (table
parameter T_LTAP_VB). All database changes due to the transfer order
have already been performed. The transfer order is created.
With this user exit, you can update your own tables or trigger follow-up
actions. Although changes made to table T_LTAP_VB do not have any
effect, they should still not be made.
I hope this information helps!
Regards
Martin
