How to make a work order in TECO raise MRP's NETCH flag in MD21

Hi experts,

I've this request: what can I do for make the action of putting TECO a work order to raise the flag of Net Change Planning for that material in tcode MD21?

This is the scenario: from monday to friday, every night runs the NETCH MRP. During the week-end runs the NEUPL MRP. Work orders are set TECO every day. My custumer need's that if one day a work order is technical concluded, that night the MRP NETCH plan that material.

I know that that's a list of action related to a material that raise the MRP NETCH flag in MD21 but the Technical Conclusion of a work order isn't in that list.

Are there any way to update that list?

I know I can use a BAdI to do it at the update of the work order, but first, I would like to explore other options.

Thank's in advance
