Partial substitution of alternative item material

Posted on Jul 30, 2010 at 12:44 PM 29 Views

Dear guru.

I have a bom with two alternative item (A and B) with same group.

I need that mrp create dependent requirement only for A and nothing for B.

After atp check if B is available and A isnu2019t available I need that the system create requirement for B for the available quantity and create requirement for A for the remained quantity.

How can I set the alternative item data group of bom for these two component ?

Thanks.

    Hi,

    I hope that I understood you right;

    The set up of the alternative item group in the BOM should be like this:

    Priority - 1 for A, 2 for B

    Strategy - 1 for both

    Usage Prob. - blank for both

    Alternative item group - same for both

    Now this works like this:

    MRP will always plan A.

    When ATP is checked in production order it looks first for A. If A not available or available quantity not enough, then it looks for B.

    Be aware of system behavior when using this with backflush and overproduction! There is a note on this!

    Regards,

    Mario

    Hi.

    Thanks for your interesting.

    With your suggestion the system donu2019t have the behavior that I need. If A and B arenu2019t available the system donu2019t create any dependent requirement for nothing.

    I have tried with this setting :

    Priority - 1 for A, 2 for B

    Strategy - 2 for both

    Usage Prob. u2013 100 for A blank for B

    Alternative item group - same for both

    If A and B arenu2019t available all the dependent requirement is create for A.

    If B are completely available and A not , all the dependent requirement is create for B.

    The problem is concerning when A isnu2019t available and B is partially available , all the dependent requirement is create for A , the system donu2019t split the requirements.

    Can you help me ?
