Use case
When development it can be very useful to inspect the XML to know:
- Has the code taken effect?
- Which values are available in the request you are reading
Flow
- It is always Mobile that initiates the communication with a Request
- Business Central is always the responding party
Inspect Mobile XML Communication
Go to the "Mobile Document Queue"-page.

You can use the Mobile Document Queue List to handle and inspect failed mobile documents. |
Finding the right mobile document
Isolate for the right entry, using columns like Document Type, Registration Type or Status Filters

The Response XML contains both the Error message and Error call stack.
How to interpret the Error Call Stack
The beginning of the error call stack is where the process failed. This allows you to:
Isolate the source of the erroneous code
Identify where to set breakpoints for debugging, see Debugging
Third-party applications can be the cause of the error
The call stack can point to non-MobileWMS extensions. Look for "ExtensionName by Publisher".
This points to an issue outside of Mobile WMS. In Example, the Error Call Stack points to the Extension ShipIT 365 by IDYN B.V.

When reprocessing fails, you will see the error on the screen.
More information is available in Copy details.
Select "Copy Details"
Paste the text to a text editor or an ongoing Service Desk ticket if you have trouble pinpointing the root cause of the Error.

Inspect Error Call Stack and Debug
When a request ends in Status: Error, it will remain so until it succeeds. Subsequent attempts from mobile will only attempt to re-process this original request.
You can use this to inspect the Call stack and initiate debugging.
