Contract not visible in Account Balance screen in UI- Role- Utility IC Agen

HI Gurus

We are in a CRM ISU implementation. We have generated bill against contract and invoice also at CA level in ISU. We are able to see the open & due amounts in Account Balance screen in CRM against the Business Agreement only. There is standard field Contract also available in CRM in account balance screen. But we do not see any contract in the field.

Middle ware is in place and data is in sync.Data flow of BP, BA & contract is from CRM to ISU

Please guide how the value of contract is displayed in CRM.

Thanks

Ritesh
