Exclude Material Reservations from ATP calculation


Hi All

I'm a bit stuck while trying to set up availability checking for material reservations created from PM maintenance orders. In the company I am working for a reservation cannot be withdrawn until certain critera have been met (this is an enhancement which assigns a delivery address and other attributes). I am trying to prevent reservations from reserving stock until these criteria have been met and I have hit a brick wall.

With a normal material reservation I would simply clear the movement allowed flag until these critera are met and configure the availability check to only include withdrawable reservations (T441V-ARREP = A). However it appears that for material reservations created from a PM order it is not possible to clear the movement allowed flag so I am looking for BADI where I can check each reservation item for the critera and exclude from the ATP calculation if the critera is not met.

I cannot hold back release of the PM order until the critera is met because the reservations are required for planning and procurement purposes.

Can anybody offer advice or point me towards a suitable BADI? I've been looking for hours and don't seem to be getting anywhere.

Many Thanks
