Field Bill Aggregator in Business Agreement

HI Experts,

This is part of my SAP CRM-ISU project,

I am not able to locate a field : Bill Aggregator field in SAP CRM Business Agreement but there is a corresponding field in SAP ISU in Contract Account level (field name: Bill Consolidator).

Please help me to find the filed: Bill Aggregator field in SAP CRM in Web UI at Business Agreement level.

Thanks

Madhu
