Planned Order Dates based on WBS-element?

Hi all,

At our customer here, we are trying to set up an engineer-to-order flow by using the PS-module but I'm still having some questions about the planned order dates.

In the WBS-element we enter on what day the 'module' should be finished and a number of 'assembly' days. This would mean that at the 'start' date of the WBS-element, all the pieces/components that have to be produced or bought should be ready and available for use.

Now i'm wondering if it is possible to use the standard within SAP to copy the 'Start Date' of the WBS-element into the subordinate Planned Orders (of a specific MRP-controller, ...).

Thank you for helping me out with this question!

Kind Regards,

    Hello Guy

    Usually, in the ETO process, the PS network order will drive reservations, which would be relevant to MRP.

    MRP will consider those reservations as a requirement and it will generate planned orders to cover the requirements. Depending on your settings, MRP may consider the network reservation date as the planned order finish date and schedule it backwards to calculate the start date.

    Besides that, there is no standard setting to make the planned order dates to match the WBS dates.

      You can use transaction CN33 to transfer the BOM components to the project. It is possible to use reference points, so that the BOM components are directly transferred to the network where they will be used.

      In addition, we generally deliver the subassemblies directly from the project using transaction CNS0.

    When you are assign components to the project activity,system will create reservations against the project based on the strategy you have define in material master.Try to run MRP by using tcode MD51-Project Planning-Multi level against WBS element.

    Long time back I have worked in strategy 51 i.e Plng w/o final assembly / project settl for ETO scenario where planned order start and end dates get copied from WBS start and end dates.Please check and revert.
