Here is a better example:
I was working on this problem for 8.82 PL17 and could not get it to work despite using SAP's official note. The note did not give enough of an example to get me going so here is my example files.
You need three:
OIGN
IGN1
SRNT

I purposefully added a lot of data so you could see where I initially went wrong. You will have people tell you that IGN1.LineNum should be blank if you are importing. This might be right in terms of a sales order or other marketing document, but for the sake of importing Goods Receipts with serial numbers it's incorrect. You need to sequentially order your IGN1.LineNum column. Then this column needs to match SRNT.BaseLineNumber so if there are multiple serials each of the rows in the SRNT document in the SRNT.BaseLineNumber column needs to match the rows in the IGN1 document.
What struck me as not being intuitive is that SRNT.LineNum has to be sequentially numbered DESPITE the SRNT.BaseLineNumber being matched to the rows. I was trying to sequentially number the SRNT.LineNum as you would for a contact in a customer import.
Something in SRNT like:
ParentKey | LineNum | InternalSerialNumber | BaseLineNumber |
| DocNum | LineNum | DistNumber | DocLineNum |
| 1 | 0 | 1593250 | 0 |
| 1 | 0 | 1409857 | 1 |
| 1 | 0 | 341085 | 2 |

This is incorrect though. All I needed to do was to sequentially number the SRNT.LineNum column without caring about the correlation to the number of serials and it worked fine (see my original three sheets at the top).
I hope this helps someone from spending five hours working on a data import.
Let me know if this all makes sense, Mike
