We have two documents type NB & ZNB for Purchase Requisition.
1) We are using Doc type NB for Requisition which is Triggered /created through APO/MRP.
2) Doc type ZNB we are using for Requisition which is created manually.
Now what we want is to Restrict Doc type NB, if someone tries to create Requisition manually through it as it is only used in case of Requisition Triggered from APO/MRP.
Do we have any Standard Config setup available to restrict this or we need help from technical Consultant to go for some Enhancement? Please Suggest.
