    Hi Tanapong,

    You can use the MD_CHANGE_MRP_DATA BAdI to consider or to exclude special MRP elements other than the ones that are defined in the standard system. You can do this by using BAdi MD_CHANGE_MRP_DATA method CONSIDER_RESB. Please read the documentation of this BAdi also refer the modification from note 37697.

    Hello

    The standard option would be to set a storage location excluded to MRP and direct these reservations to this storage location. You can do that on tab MRP4 of the material master.

    Another option is to use BAdI MD_CHANGE_MRP_DATA to set these reservations as non-relevant to MRP.

    • Hi Tanapong,

      OPJJ Availability check control is not relevant for MRP. OPJJ setting only useful for ATP check. MRP consider the setting of OPPI to consider the stock in MRP calculation. MRP has nothing to do with Availability check control OPJJ.

    Why would they create two requirement requests (Independent req. + Manual reservation) for one actual requirement? The process itself doesn't seem right to me.

    I would suggest your manual material reservation person to un-check the check mark for "Movement Allowed" while creating Material reservation. This way only PIR gets netted during MRP calculations.
