Hi
Trying to update a field in a blanket order sales line, via web-service.
To set field "A", i must have set field "B". This is the behaviour (custom) in Navision.
Problem is that when i send the UPDATE call via SOAP, it sets A and B at the same time, causing NAV to send a error message. If i set just B, it is okay. If i set A just after, the key is used and i get a error stating someone else has modified the order.
I do not want to read the entire order again, to issue another UPDATE to field A. Do i really need to?
Also, to identify the specific sales line, i use its key. Is it another value i could/should use instead, who could predict somehow? Saves some read/iteration, i could just read the initial sales order header key and figure out number of linesm and then calculate the id of the line i want to change, or something like that.
Thanks
Kim

I found OData to be faster and giving more choices if you only use standard page/report/query services.
I picked Odata for my use case, and there is no need to specify a KEY if you UPDATE a record. Sure it makes sense to do so if you update a record that might be updated by someone else...
So with ODATA, if you send HTTP Header:
If-Match: *
.. instead of a key which looks something like ...
If-Match: W/"'24%3BlQEAAACN1ZNxAAAAAAAAAA%3D%3D9%3B1147927720%3B'"
..then the KEY is not checked and the call succeeds.
Same for DELETE ops.
