SCHEDULING AGREEMENT AND SCHEDULING LINE Delivery Date determination logic by MRP

Dear all,

I'm using Scheduling Agreement + relevant Schedule Line creation (done automatically by MRP run) where I have the following settings for all the involved materials:

1) in View MRP2 of Material Master mngmt, the "Planned Delivery Time" & the "GR Processing Time" are both set to "0" days

2) When MRP runs, it allocates the computed need, to the FIRST day of the week and so, ever on MONDAY

3) Source List & Quota arrangement for the materials involved are maintained

What I see, which is quite strange is that:

a) in ALL cases, for all the materials planned, the MRP correctly ALLOCATE them needs (the "VSFB Independent Requirements) to the weekly day MONDAY but..

b) in some cases (for some materials), the Delivery Date automatically assigned by MRP IS NOT a MONDAY (as often done) but another week day (more often FRIDAY).

Any idea about the way MRP does to compute that date? Which is the behavior applied by the MRP tool in this case?

many thanks in advance for any suggestion about,

best regards,

Loris

    Hi Loris,

    Please check the Lot size procedure you have set up in this materials in MRP views of material master data. It looks like using a lot size procedure with planning calendars - this is locally set for each material and defines how SLines are agregated.
