PP MRP Seasonal VS

Hello experts,

I am trying to generate a seasonal MRP scenario type VS, but when I do the planning run (MD03), no action occurs.

Although the configuration (OMDQ) tells me that there is no need to preview the material, during execution it asks for it to be done. However, even when I make the forecast, nothing happens. What am I doing wrong ?

Could you help me to simulate a scenario? Thank you.

MM03 - MRP 1

MM03 - MRP 2



The calendar 002 is not relevant, u can use anyone.


Trying acess MD04

Trying execute MD03

Thanks you.

    You are running a time-phased MRP type, which means that you first need to create the forecast tabs in the material master and then run the forecast for your material.

    If you don't want to use a forecast, but still want to use time-phased MRP, you can create a custom MRP Type as a copy of VS and check the flag time-phased w. reqs.

    By the way, what is your business requirement to use time-phased MRP? I usually prefer to use a regular MRP type PD and lot-sizing PK when I need to have deliveries in specific days of the week.

    You planning calendar is valid until 30.06.2020 and you have forecast until period 09.2020.

    So please extend the planning calendar validity in future ex - 30.06.2022 and then re-execute forecast and MRP run.

    And the check message 61059: 'Please carry out forecast for material & in plant appears or not.

    Best Regards

    • Hello Caetano,

      Thanks and sorry for the delay.

      Yes, I did it some days ago. The message appears after execute the FM "MATERIAL_READ", and the system checks if the fields MARA-SAISO and MARA-SAISJ have value.

      After this, the error appears.

      that's why I think the forecast he is talking about (when the parameters in the OMDQ are "No forecast") is another forecast, other than the one in the master material.
