MRP behavior with planning calendar

Dear Mr. Caetano Almeida,

Greetings! Hope you are doing good.

This Question is related to the thread "https://archive.sap.com/discussions/thread/3577436", it is clear that the PDT for the external planned materials are in calendar days and not based on factory calendar.

Also would you please clarify that when MRP switching from backward scheduling to forward scheduling will it consider the start day as a Non-working day? For example, 13.02.2018(Tuesday) is the date where MRP needs to plan a schedule line with PDT of 30 days (No GRP or any other cushions) and with delivery cycle as Tuesday. Now, MRP is running @ 13.01.2018(Saturday) but MRP did not start scheduling on 13.01 rather it started from 15.01 and proposes 20.02 as delivery date with Exception "30: Reschedule in" Is this a standard behavior? Thanks for your reply in advance.

Regards,

Chinna

    Hello

    Even though your requirement is on a non-working day, MRP pushes it to the next working-day during net requirements calculation. Therefore, it starts the scheduling on 15.01.

    Dear Mr. Caetano Almeida,

    Greetings!

    Is there any OSS notes available explaining the MRP will not start the forward scheduling in a non-working day.
