Plan order creation for Griege booking order

Hi Team,

I have one requirement to change plan order data at the time of MRP run. For this i am using BADI "MD_PLDORD_CHANGE".

This is working fine for sales order and  Griege booking order ( VA41 & VA42 ) at the time of first MRP run. But when i make changes in Griege booking order and try to run MRP again that time BADI (MD_PLDORD_CHANGE) is not triggering, So my Plan order having the old data.

After the MRP run we are deleting the schedule line no and creating new, for the new schedule line we are giving new schedule line no (As per client requirement Schedule line no should be unique).

Please suggest me how i can change my plan order data.

Thanks,

Venkadesh
