LA confirmation date in MD04 Supplying plant side

Hi,

We are using Stock Transfer Purchase orders (STPO) to procure materials from inter-co production plant. We place a STPO on the production plant. This is visible as Order DS at production plant stock requirement list (MD04)

Based on the info/confirmation from the production plant we enter a confirmation in the STPO, Conf.control=shipping notif conf.category=LA=inbound delv. (relevant for MRP). Here we input a different date for the confirmation then,
The new confirmed date is now visible in our receiving plant, but not in production plant under MD04.

The MD04 still displays the same old original date for the STPO based on delivery date and not the revised confirmation date in MD04.

Any input will be welcome,

Thanks,

Ju
