Change in Expected Delivery date (EDD) field in the PO after final release

Hello Experts,

There is a business requirement, whereby after PO final release is completed & when the PO is released for further processing, no further changes should be possible, except for the expected delivery date (EDD) field in the Delivery schedule tab of the PO Item details. Other than this, no changes should be possible in the PO, neither qty, nor price, not even the simple PO text should be allowed to get changed. In other words no field should be allowed to change.

Ideally, except the EDD field, other all fields should be in grey mode, or atleast changes in any of the PO fields (except EDD) should not be allowed to get saved after the PO is final released.

Please let me know if SAP provides any such facility, whereby you can selectively choose certain fields (like EDD field) on which Release Strategy should not be applied & changes should be allowed in these fields even after PO final release.

Thanks in advance,

Zafar.
