Date/Time Calculation on Shipping Tab of SO Schedule Line

[former_member576876]

Sale order is entered outside the lead time and ATPs to that date. On the shipping tab of the schedule line, the material availability date and time are 2/14 and 00:00. MRP runs and we have the sales order and associated planned order scheduled for 2/14 on the MD04 screen.

The sales order rescheduling runs prior to start of business the next morning. The order is now requested under lead time and generates a second schedule line. This is all fine and good. The problem is that now in the MD04 screen, the sales order material availability date on schedule line 1 has moved in one day to 2/13. The planned order is still scheduled on 2/14 and is now not aligned. My guess is that this has something to do with the switch between backward and forward scheduling. Can anyone provide input here?

Second, when the date moves in, the time moves from 00:00 hours to 01:00 hours. Where is the 01:00 coming from?

I've tried to search the web for input as well as SAP's knowledge base and have come up empty.

It depends on Configuration parameters for Shipping Point and also you need to check IMG under Logistics Execution > Shipping > Scheduling > Maintain Working Hours, Route determination etc.,

Good call. I had checked this in one system, but not in my test system and needed to make some changes. The shift from 00:00 to 01:00 appears to be due to time zone differences. Plant and Ship-To in the same time zone creates 00:00. Plant and Ship-To in different times zones, EST and CST respectively, creates 01:00. What is interesting is that when I increased the lead time and re-ATP'd the order, the confirmed date went out one day as expected. However, the time went from 01:00 to 00:00.
