Setup Group not updated in APO

Hello,

I have a Setup Group defined in a particular Group Counter in the Routing the R/3 system, it has been CIF'ed to APO. However, I used the same Setup Group to another Group Counter of the same Material in R/3. However, in APO it didn't take effect or not been updated.

I would like to know if a Setup Group be used to one Group Counter only? Since the changes didn't take effect in APO, I know it can be modified in APO, however I am not certain if using the same Setup Group will affect the planning process in APO.

Please enlighten me on this.

Thanks,

Nap
