• In purchase order ABC, an attempt is being made to copy an item with multiple cost assignments (MCA) and a reference to a Purchase Request.
• In this case, we do not allow the change of assignment.

• As part of the design, the GSA items would be created based on the account assignment data in the case of MCA.
• For example, if it is 90% CC1 and 10% CC2, then there would be 2 GSA items, and the posting would be made to Accounting.
• Now changing the same in purchase order, per example from CC to PRO, would result in posting to different ledgers than that of what was requested as part of Shopping cart and/or Purchase Request. 
• The same issue would not occur when attempting to copy an item with only one Account Assignment
