DI Server update document lines

[Former Member]

Hi, I have a few time using DI Server and have a question, if I have a document with 10 lines saved in sap and i update the document with DI Server and send only 1 line in the document lines into the xml. After the document was saved in sap, it continue having 10 lines. I expected have only one line.

So, my questions is how can i do to remove the extra lines or just save the lines that i need and "automatically" remove the others.

Edit:

I have checked this post

But when I try to save, I receive this message:
