SAP Business ByDesign
Reproducing the Issue
Go to the Purchase Requests and Orders work center
Go to the Purchase Order view and select the relevant Purchase Order
Select Edit and navigate to Items tab
Select the line item and change the Quantity
Select Send Update and error appears
System shows an error message because for Purchase Order there are Inbound Delivery Notification present in the system however no actual Delivery Document is created. System stop changes on Purchase Order, when there are only Delivery Notification exist but not actual Delivery Document because if we allow changes on Purchase Order then order will go for an approval then no changes on Purchase Order are allowed. In mean time, if user creates actual delivery document ,then information to Purchase Order from Inbound delivery will not be updated. This will create an inconsistency in the purchase order document.
You can create actual Inbound Delivery documents for the items which has an Inbound Delivery Notification and then changes on the Purchase Order is allowed. This is an expected behavior.
