Updated Bill Of Materials doesn't update Contract

Hi Gurus,

Here is a problem that is driving my client crazy.

I have a bill of material that links a material A to a material B. Now the number of units that matches one material to the other has been changed but the cotracts that had been already created do not get updated according to the updated BOM.

Does anybody know if there is a Report that runs un update on BOM data on contracts?

Or maybe there is a way, I dont know, to update the "Commponent quantity" field on contracts through MASS transaction...

Good appreciate in help. Thanks in advance.

Cheers
