Multiple lot number on one RMA line

Can we create Return order where we can pass multiple lot number on single RMA line using FBDI ?

for example :create a RMA line with 3 qty where 1 qty has LOTA and 2 qty has LOTB?

I tested by creating return order with this scenario but order failed with error message : "The lot or serial number lines couldn't be split. See the inventory log for more details."
