SAP FSCM BP Account grouping

Good day,

May you please help, we need to update field CUST_GROUP (table UKMBP_CMS_SGM), ideally we would like to populate this field with a customer group.This will be used to check the credit limit utilization for all the customers in a group using report UKM_MALUS_DSP - Credit Limit Utilization. May you please advise on how to activate this field so tha it can be populated on the BP master data.

Thanks.

Regards,

Noni
