LSMW: How to add BAPISDDELSCHED_EX to LSMW using E1SALESORDER_CREATEFROMDAT2?

Hello *,

I'm trying to migrate SD Schedule Agreements using LSMW and E1SALESORDER_CREATEFROMDAT2. In this structure, there is no segment related to table VBLB (SD Document Schedule Header), but I found a standalone BAPI ( BAPISDDELSCHED_EX) which does this.

My question is how can I integrate this second BAPI into my LSMW, so that I have these fields also mapped, so I can send the complete document?

Looking forward for your answer!
