Re: MRP Vs Material Availability Check in SAP

Hi Rupesh,

Thank you for providing the glimpse of difference between ATP (eg: which we do it in production order - Material Availability Check) & MRP Net Requirements Calculation.

So i am understanding as below:

1. For available stock calculation during MRP Run, OPJJ & OPJK settings will NOT be considered. Only OPPI settings will be considered during MRP run for available stock calculation.

2. OPJJ & OPJK setting will be considered only for ATP check in production order , process order, sale order etc. For ATP check in production order, OPPI settings will NOT be considered.

Is the above points correct?

thanks
