Planned orders generated by MRP should be for the same requirement date

Hi All,

Have a requirement with MRP in REM, to trigger planned orders as per the below

Have requirements for 3 months like 50, 50 and 50 for each month.

MRP created planned orders as per the requirement, now manually changed the Planned orders to 30 quantity and marked as firmed.

so there will be open requirement every month 20 quantity, then total 60 quantity for 3 months, for them no planned orders.

After running MRP second time system creating single planned order in the last month for the remaining 60 open quantity.

Expected: system should create planned order for each month for open quantity of 20 quantity after running MRP second time.

Please provide your valuable inputs.

Thanks in advance

Regards,

Rithesh.
