Backdated IMT are not allowed for requested delivery date and shipping date

Summary: We are not able to backdate the shipping transaction and receiving transactions in an IMT flow.

Is there any guidance regarding this requirement?

We are trying to record backdated Internal Material Transfers (IMT) to ensure the inventory transactions are reflected correctly in previously opened periods.

Our current process is:

• Create a requisition.
• A Transfer Order is generated.
• Ship the items from the source organization.
• Receive them at the destination organization.

However, we are facing an issue with backdating the transaction. The Scheduled Ship Date on the shipment line (Outbound Shipment) is controlled by the Transfer Order and is not editable by default. We used VBS to make the field editable, but the system still does not allow us to select a backdated shipping date.
