Thanks unfortunately it can include returns and transfer orders. It's effectively a file from a carrier containing NS document numbers as reference. Sometimes I can link to NS transaction sometimes not as it may say So1234-1 and I've created a Sublist allowing user to choose correct entries. At the moment found a way but will need to limit file to 150 lines. Looking to see if someone knows any other way. But thanks for suggestion. I suppose I could split it into document types and us the technique not a bad idea
