Can I process each record of a BO, based on the records found in a query of another BO? SO the process would be to Run a query of BO_A and filter down to the records you want. Each of these records contain a key field. Now based the this query results, find records in a second BO_B where BO_B. Key_field = BO_A.Key_field and set another field in BO B.
BO_A.Key_Field
BO_A.Description
BO_A.System
BO_A.Account
BO_A.Key_Field
BO_B.Category
Query BO_A and filter down to the records you want by Description, System, Account ect. Now using the results find each record in BO_B wher the Key Fields match and set the Category in BO_B to some value.
I've managed to pass the filtered BO_A to a process. FInd BO_B based on the key field and update the category. but only for the first record. Not all the records in the passed query results.
