Isseu regarding MRP calculation.

[Former Member]

Hi Gurus,

We have MTS scenario with strategy 10 ,requirement type LSF , in MD61 PIR are present from 01 /01/2011 till today , but when i check in MD04 only requirments from 01/04/2011 are taken into consideration ( for LSF requirment after 01/04 system is showing -ve qty and plan order are generated for these independent requirement ) , i want to know why PIR from 01/04/2011 are taken into account and why older PIR are not considered.

Current stock is 0 and planning time fence in 30 days and planning horizon is 100 days,, please help me understand why older demands are not taken for calculations.

Thank you,

Hi.

I assume you have run the MRP with the processing key NETPL (Net Change in Planning Horizon). And as you have define planning horizon 100 Days that's why system is taking the requirement for only 100 days. If you want to have total requirement have to consider use MRP processing key NETCH (Net Change in Total Horizon).
