View Request and Response XML and Error Call Stack

Description

You can use the Mobile Document Queue List to handle and inspect failed mobile documents.

Finding the right mobile document

Open Mobile Document Queue List
Isolate for the right entry, using columns like Document Type, Registration Type or Status Filters

View Error Message and Call Stack

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 Attach and Debugarchived

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.

Share the Error and Call Stack with Tasklet

You can copy these files to the ticket if you have an ongoing Service Desk ticket and have trouble pinpointing the root cause of the Error.

How to Reprocess Mobile Documents

You can reprocess failed mobile documents from the Mobile Document Queue List in Business Central.
This will show the error message on your screen.

Note: The code is executed in the context of the current user

Select Process > Process Document

Use “Copy Details” to view more additional information

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.

How to interpret Request XML

The mobile app request is likely the most interesting for development. The request shows the values available.

Here are fields "MyDate", "MyText" available in a request for an Unplanned Function named "MyUnplanned".

<?xml version="1.0" encoding="utf-8"?>
