Receivable Receipt Recommendation using Auto match rule set

During auto lock box receipt process- Receivables applies receipts to transactions based on the transaction information provided. But Auto match rule, showing some more transaction as recommended with weighted average %.

But our requirement is , to disable the Auto match rule, When I pass Transaction number in the auto lock box file, Same transaction should be applied for the receipt.

I don’t want recommendation to show some more transaction. What setup I can do in the Auto match rule set – like recommendation and weighted average %. So my auto lock box process will apply to only to the transaction passed in file
