Cash Application: Negative RI creating RB

Another 9.2 issue

We use the R03B551/R03B50 to apply both ACH and Lockbox receipts.

We just got RM's and negative RI's working on 9.2 (Note, they now have to be ran together unlike in 9.2)

Today, we had 3 negative RI's create RB's for the same customer. This is the first time it has happened in the month since we got it working.

This is the first place I have worked at that uses negative RI's. Is there anything on the Customer or System setups that I should be looking for?

Thank in advance
