RMA Num on the Sales Order Line

Does anyone know if the RMA Num on the Sales Order Line Detail is linked anywhere? Does it make a difference if this is populated or not? Is it just for reference?

I believe it’s for tracking replacement orders for RMA’d items. It links back to the RMA, which itself links back to the original sales order. It’s certainly not required, but it’s certainly useful to have all the links in the chain.

We don’t use it. We just reopen the original SO line/release and make a second shipment at no cost on the original line. We rarely have RMA’s anyway. Defects are caught before shipment.
