Invoice Split due to different incoterms 2
Hello SD experts..
Kindly advise on the following situation.
we are making supplemetary invoice with ref of invoice which could be more than one sometimes.
Further more in first invoice we have put incoterm 2 as a BY ROAD. In 2nd inovice we have put incoterm 2 as BY TRAIN & in 3rd it is BY AIR.
So when we try to make supplementay invoice with ref to these 3 invoice ( we want to make only 1 supplemetary invoice) it is getting split saying " different header data- Incoterms 2"
What settings I have to change.?
Thanks & Regards
