MRP to consider WIP

Hi Experts,

I do understand that WIP is "NOT" stock in SAP. but in our process WIP stays for long time.

for example

I have a production order and I confirmed 10 quantity for operation 10. that means my wip for the material is 10.

Then I get a requirement of 10 for the material. when I run MRP , it creates procurement proposal for 10 again. but in reality I know 10 will be GR'ed from the production order in a week. so I want MRP to consider the wip stock and not create procurement proposal.

how can I achieve this? user exit in mrp? or any other workarounds?

    Hello SCM,

    One idea could be to use Time Fence in order to define a Frozen horizon for the MRP.

    For example, if you know that you can have a duration of 10 days, you can use a time fence of 10 days. This way if you have a requirement inside that horizon, by using time fence you will avoid the creation of new planned order inside the Time Fence.

    Kind Regards,

    ??? MRP will always consider a production order that will be received in the future as a supply element, whether they have confirmations or not. This is the default standard behavior.

    If you are getting new planned orders for requirements that are already being supplied by an existing production order, then the most likely problem is that your rescheduling horizon is not configured to meet your business requirements. OMDW. Read the IMG help for "Define Rescheduling Check", or just look at SAP online help for "Rescheduling Horizon". Probably you should increase the horizon from what it is today in your system. Make sure "production order" is selected as one of the fixed elements considered.

    Best Regards,
