AutoMatch without any References, based on Customer only

Summary:

We are using Create Receipts in Spreadsheet ADFdi and loading receipts.

We are populating on the template Receipt Number, Receipt Amount, Accounting Date and Customer Account Number. We are not using any references, because we have none. We are looking for AutoMatch to apply to oldest transaction.

We are able to upload receipts batch, we can post it, we then run "Apply Receipts Using AutoMatch" by selecting Business Unit (rest left as default).

AutoMatch will provide recommendation, sometimes a single recommendation which is above threshold. But it is not auto applying the receipt to the transaction. The receipts will most likely be lower in amount than the transaction, so customers are part paying their invoices.
