Differentiating the orders in SNP based on number range but same category

Hi,

There is temporary requirement where we need to exclude planning for certain type of STOs/ASNs from heuristics planning. The categories are same i.e. SAP std categories but number range is different and originating plant is different. We can say that i want filter out the STOs and ASNs originating from particular plant.

Is there any other way than to exclude it from CIF (will have to use user exit) OR through macro functions?

Appreciate your thinking time for this.

Regards

Alhad
