We are currently not able to manage schedule ship date proposed by ATP when our warehouse is closed. For example , we would like that ATP doesn't propose any schedule ship date for the first of May , which is a non working day in France. The constraint is that we don't want our purchase need by date to be impacted by the process.
I tried to closed one day in FR1 calendar and, after testing with order management, it appears that ATP didn't propose the closed day, so that's fine, but, our purchase order lead time was increased of 1 day and this is not what we expected.
Can you help us to find the right process.
