Welcome
Hello,
Can i add a new sheet to the migration file please ?
I'm trying to add "contact person" sheet for vendor, since it is available only for customers.
BG
Hello Sara,
What do you mean by sheet ?
You can add a new field by using the migration Object modeler and map the field if needed.
Thanks,
Vijay
Hello,
This is the sheet that i want to add in the standard migration file, not only a filed.

Sara
Try to customize the Vendor Migration object using the MOM and use the object in Migration Cockpit it will appear automatically there.

I am trying to use LTMC for material PO upload and its successful. But, I am stuck to upload service PO as there is no place holder in default LTMC template for open PO in LTMC for uploading service PO.

Can you please raise a question in the Community as this related to a specific error with more explanation ?

Hello Vijaya,
We are using 1909 version of LTMC. I am uploading initial stock.
But when checked template of material inventory balance, I do not have material number as key field in the template whereas I see material number as a key field in earlier version. Instead I have Technical Document Number MBLNR as a key field in header and in Item, I have Technical Document Number (MBLNR) and Technical Item Number (POSNR) as a key field.
I am not sure, what should be passed here in MBLNR and POSNR as I need to pass material to upload stock.
May be this is difference is due to latest version of LTMC.
Could you please help me with this. Thanks in advance!
Vijay
Hi Vijaya,
like for the subroutines in the event-based rules, where can i check the abap code in there, since there is no response when i am trying to double click them, and can i also make some change or add enhancement there?
thanks and looking forward.
for example as in the following picture:
