Your client, a banking organization, currently uses different transaction systems for various types of loans, including vehicle loans, personal loans, education loans, and housing loans. The client has already implemented other subledger applications including payable, assets, and expenses.
You have been hired as a consultant to help them implement the Accounting Hub solution for streamlining the accounting entries from the source system. One of their requirements is to track the overall loan amount disbursed by each loan officer. You decide to use the supporting references functionality to achieve this requirement. However, when you try to define the loan officer as a supporting reference, the add option is disabled.
