Reynolds shows multiple sales.....

Hi everyone, trying to determine why Reynolds shows multiple sales of one part to the same customer.
For instance, we sold a set of brake pads and a set of rotors on an R/O that was customer pay. Looking in 3651 shows that the parts were billed internal.
It shows up in 2024 as another sale, same R/O. It's affecting how these parts come back in on a stock order.
We've got this stuff on RIM, so it looks like we're selling more than we're buying from GM.
How can we correct this?
