Hi @ken miles 

I guess Weekly Debtors report is not a standard report. It must be created in your environment. So validate the report parameters and criteria in Business Reporter excel add-in.

HI @ken miles,

Sharing below extract from e-learning materials since U asked about the purpose of the report. 

Customer Ledger Open Items Report

This report displays all unpaid invoices and customer payments on account. It is useful for internal checking against the general ledger. You can display total customer balances or detailed information about each customer. You can also select by code string. For example, if your company needs to follow up on the code part used for cost centers, you can specify a code part value and compare the report against the general ledger. When you print the report, you can specify whether it will be sorted by the ledger account, customer ID, or customer name. 

Weekly Debtor Report - I also think it is a customized report & you need to check the logic & purpose internally.
