To view the Accounts Receivable Group Details associated with an invoice category and the sequence in which payments are applied towards them:
Right-click on an existing group and select View Details. This displays the Accounts Receivable Group Details window.

This window displays the following information:
Accts Recv Group Detail ID
System-generated identifier that uniquely identifies the accounts receivable group.
Accounts Recv Group
Name of the Accounts Receivable group.
Invoice Category
Category to be paid per the sequence number.
Sequence Number
Establishes the payment order relative to other Invoice Categories.
Note
If the invoice categories are not assigned to the customer's Accounts Receivable Group, the standard IDI platform rule will take affect and the “oldest balance first” will be paid off. Multiple balance amounts will be paid in an arbitrary order if they (1) have different invoice categories, (2) are the same age (created in the same invoice), and (3) are not covered by the customer's Accounts Receivable Group details.
To add or modify details, right-click on a row and select New or Edit. This displays the Add/Edit Accounts Receivable Group Detail window.

Select an Invoice Category from the drop-down list and enter a Sequence Number.
Click Save.
