Hi Mahendra,
I suppose you are sure the vendor and material are CIFed. Have you check this?
I also suppose that when you run CFM1, the system finds your schedule agreement.
So I would review the change pointer.
Run BD22 and make sure that all processed and obsolete change pointers are deleted. If you have a similar problem with the system, go to BD50 and check if change pointer are active.
Kind Regards,
Mariano
