Error during GR against delivery.
while doing a GR for a delivery created from DC to a Store, I am getting an error at store as " Enter goods receipts for Vendor only". I have checked the delivery which is meant for that store only. Also the Delivery creation has been done correctly against the STO.
Another interesting fact is, during the GRN through MB0A Transaction, after the error comes, if I click on the Purchase orders tab on the top Left and close it and then try to go ahead with the GR of the delivery then it allows the GRN. I feel it is re-determining the Vendor data from somewhere.
According to my undertstanding, in case of delivery created against the STO, the vendor should be automatically picked up as the supplying site which probabaly is not happening during the first attempt to do GR.
Later it redetermines the data and allows the GR.
Kindly help me in finding where exactly the problem must be i.e in the delivery or the STO or somewhere else???
