Kit to Stock - Error in Inbound Delivery

Hi Gurus,

In Kit to Stock, the Outbound and Inbound delivery is getting created but both are in locked state.

The inbound delivery is in red (locked) and is under PPF tab shows the error message as " Automatically Create VAS for Kit Creation from Stock"

in SLG1, I get the error message as "

Error during automatic generation of a VAS order (PO)"

and

PPF: it has not yet been possible to create a VAS order

I have already maintained the field PPO and VAS field in reference profile both for Document type and Item type. But still getting the same error message.

I think the system is trying to check the reference of Production Order in Inbound Delivery, but it is not getting it.

Any suggestions ??

Regards
