AR LockBox : Multiple cash receipts for installment invoice was not applied to installments

Hello All,

Kindly help me with sorting out this issue.

Following is the scenario,

An Invoice with 12 monthly installments was uploaded and then 12 cash receipts were uploaded via LockBox.

The monthly installment amount is 1,398.58

1st cash receipt is 1,233.00 and was fully applied to the 1st installment.

2nd cash receipt is 1,233.00. Out of that 165.58 was applied to the 1st installment so that the 1st installment would be closed. Remaining 1,067.42 was left unapplied.

3rd to 12th cash receipts were left unapplied.

We also noticed in the output file of the concurrent request "Process Lockboxes (Process Lockboxes)" that all the cash receipts were indicated as applied to Installment 1.
