3326228 - Cannot update Distribution Indicator to Single Account Assignment in Central Requisitioning

In the case of central requisitioning, we cannot update the accounting Distribution Indicator to Single Account Assignment.

On changing the distribution indicator from Distribution by Percentage to Single Account Assignment, the following error is thrown “sum of percentage>X<smaller than 100%”.

On changing the distribution indicator from Distribution on Quantity Basis to Single Account Assignment, no error is thrown but the change is not reflected in the connected system.

This is an expected behaviour in central requisitioning. 
Once the central purchase requisition has been replicated to the connected system, the accounting distribution indicator of the purchase requisition item cannot be updated to single account assignment.

This is because we use BAPI to create a purchase requisition in the connected system and the interface does not support this scenario.
