&V1&
No APO operation data is adopted in the ECC order &V1&.
To transfer dates from the APO order to the ECC order, the update of the
operation data from SAP APO to the ECC order is in many cases decisive
(Example: planned order conversion from APO).
If a date change made in SAP APO should be adopted in SAP ECC, check
further messages in the application log for integration.

The SAP error message X4220, which states "Operation data of ECC order &1 was not changed," typically occurs in the context of production planning and control when there is an attempt to modify operation data for a production order (ECC order) that has not been changed or updated in the system.
Cause: No Changes Made: The most common cause of this error is that the operation data you are trying to change has not actually been modified. This can happen if the user attempts to save changes without making any actual updates to the fields. Order Status: The production order may be in a status that does not allow changes to be made. For example, if the order is already completed or technically closed, changes to operation data may not be permitted. Authorization Issues: The user may not have the necessary authorizations to make changes to the operation data of the production order. System Configuration:
