STO: why the delivery date is not updated in ATP check after route changing?

[annafrank]

After the route is changed in STO, the delivery date is not updated in the ATP check,so the availability check refers to the old route, not to the new one.

Only after the PO is saved and opened again, the delivery date is updated and the ATP check can be calculated correctly, but the users can not work this way.

How could this problem be solved?

Thank you for your help!

This sounds confusing, how do you change the route without saving it and why do you expect then an effect if it not yet saved?

Thank you for a quick reply.

If i change the route and press enter, i hope, that the ATP check determines a new delivery date.

After the route is changed, I get a warning message 06 418 "Can delivery date be met? (Realistic delivery date: 18.12.2017)" which is shows a correct new delivery date, but in the ATP check screen the old delivery date remains.

Upd.: Now if a user makes an ATP check with wrong delivery dates in case of route changing, it can occur, that the amount of particular material in MD04 is negative. Should the users be trained and forced to save STO after the route is changed and only after that an ATP check can be started? I hoped, there could be another solution...
