Hi,  We already send a GET request to get the actual line number values. However, the problem remains as long as there is a chance that order line with lineNbr = 1 has completely different data from one GET request to the next (if the orderline has been deleted and added again like I described in my last post).  The whole problem disappears if we can be 100% sure that deleting one order line and adding a new one ALWAYS increases the lineNbr counter. In other words, there should never be an order line with lineNbr=1 if the line with lineNbr=1 was deleted at some point.  I encourage you to test this once again - I find it hard to believe that this only happens in my Visma.net client. ...

One more thing that I discovered during testing:  User creates an order line in the Visma GUI. The order line is imported to our solution, and our integration updates the order line with some unique value in the externalLink field. To do this update, the API requires that lineNbr is sent with the update request. If not, we get the following error message:  "message":"Cannot update salesOrder line without line number"   So we're back to the lineNbr problem again. Imagine if the user deletes the order line in the GUI (let's say the lineNbr is 1), then adds a new order line, and this order line gets the same lineNbr value (i.e. 1) as before (this was my original problem when I started this thread). Let's imagine that this "delete-add new line" sequence in the GUI happens BEFORE our integration has updated the original order line (with a value for externalLink). Then the value of externalLink from our system points to a now non-exsiting order line in Visma (as the original line with lineNbr 1 is deleted). This is a potential problem for our integration. Any thoughts on this?   Would it for example be possible if either lineNbr OR externalLink is required in order to update an order line?  ... View more

Oops, sorry about that! Thank's Yildirim! ... View more

Hi,    A comment regarding externalLink: It is editable in the GUI, at least in my test-environment. Is this the case for the Visma.net production environment as well? ... View more

This happens for some of our customers, i.e. more (if not all) companies.  Ok, I'll try the ERP support.  Thank you!  ... View more

Hmmm... That is strange. In my case this behaviour is consistent. It happens every time. This is what I do (all steps below are done in the GUI):  1. Create a new sales order (order type is SO in my case). Click save before adding an order line. 2. Add one order line and click save. In my test I add an order line with unit "TIME".  3. Delete the order line and click the add button again. I do not save the sales order in between.  4. The Line Number property is still 1, see attachments.    I understand that this is not directly related to the API, but it still causes some trouble for us in our integration with Visma.net.  How do I get in contact with the ERP support?  ...

Hi,    The lines were created and deleted in the Visma.net GUI, see attached image dump.   ... View more
