AX 2009 services - update operation

[ist]

Hi guys,

I have a problem with AX web service when I'm using update operation.
This is my scenario:

My query is based on two tables - parent (TestServiceHeader ) an child (TestServiceLine). Only parent datasource can be updated. (datasource property Update = Yes).
In order to use update service operation, I have to use read operation first. When I execute read operation AX returns instances for each tables (Ax...class objects) which are parts of the query. When I try to update TestServiceHeader table AX throws an exception. For this reason the instance of TestServiceLine has beeen set to null - red bordered row.
Is there any way to do that (without set to null child datasource)?

As you can see on the screenshot I want to update only header table.



Thanks,
ist

Hi ist,

I believe TestServiceLine also has a property 'action'.

When I try to update TestServiceHeader table AX throws an exception

You can find a place in code where the exception been thrown and get more ideas about what is wrong. I would also suggest to modify exception so it'll provide more information about variables etc. From my experience dealing with Aif I can say that AIf exception messages usually doesn't contain enough information.

Hi Alex,

The problem is the xml message I mean. I have made screenshots.

1. The child table class instance is set to null



2. The child table class instance is not set to null.



The second case have TestServiceLine section <TestServiceLine class="entity"> without action.
The exception is:



I found a bunch of examples regarding AIF update operation which updates the parent table only, and without set child instances to null. I can't run this examples without mentioned exception.
