search by AR contact

SOLVED

We have a customer with a lot of entities and locations with the same bill to. Within these locations, there are many contacts. So we have customers calling, stating they are with XYZ and we don't know which ship to location is related to which bill to (they all have the same bill to). We could figure it out if we could search on the contact. There are many contacts for each bill to.

Anyone know how to do this?

TIA! Jennifer
