COMAC doesnt consider availability check Z1

Hi ,

We recently changed availability check from 02 to Z1 for some materials (where in Z1 were STO materials and we required PO to be considered during planning).We have maintained scope of check for  both Z1 and 02 for PP checking rule combination (OPJJ).But unfortunately in COMAC report materials with 02 availability check are only be considered. Am not sure the reason why its not considered Z1 in COMAC?
