Checklist

Step 1: Is it a known error message?

See Error Messages.

Step 2: Inspect the Callstack and "Mobile Document Queue"

See View Request and Response XML and Error Call Stack

The call stack points to the code where the Error happens.

This code is not necessarily the source of the error - but it is still valuable information that we need to know.

The call stack is included in the XML Response

. 

Note: Tasklet support might also be able to see a limited Callstack using "Telemetry".

Step 3: Has the system been updated lately?

• Have you changed setup data?

• Have you changed extension code?

• Has Mobile WMS extension been updated?

  • Has the area been changed in recent releases? See Release Notes (Business Central)

• Has Business Central been updated?

• • Search BC Release Notes for the error message 

Step 4.1: Identify and Uninstall third-party extensions including Partner customization

Partners extend Mobile WMS with their

code. Do you have other extensions installed?
Try uninstalling them

temporarily.

Consider doing this in a sandbox (step 6) to avoid disrupting the business.

• Go to: Extension Management

• >Select

• extension

• > Select the three dots

• >Select Uninstall

• Reproduce the issue. Has the issue

• changed?
  

Step 4.2: Use "Code Coverage" to identify Partner customization

Go to

Code Coverage

.

1. Select

1. Start

2. Provoke the Error/Issue

3. Select

1. Stop

2. Inspect the result for non-base object IDs e.g. 50100 

1. Note: Mobile WMS objects are

1. numbered 6181271-6182270, so ignore them

Step 4.3: Use "Event Subscriptions" to identify Partner customization

There are two ways to view active Event subscribers to Mobile WMS.

Method 1:
Go to Mobile Document Queue List. Select Troubleshooting, > Event Subscriptions

Method 2: Go directly to the "Event Subscriptions" page by adding ?page=9510 to your URL.

• Example:

  • https://businesscentral.dynamics.com/TenantID/SandboxOrProd/?page=9510

• Example with filters:

  • https://businesscentral.dynamics.com/TenantID/SandboxOrProd/?page=9510&filter='Publisher Object ID' IS '6181271..6182270' AND 'Subscriber Codeunit ID' IS '<6181271|>6182270'

Step 5: Do you have the correct User Permissions?

See User Permissions (3/10)

Step 6: Is it isolated to one order or any order?

• Is it a single document that cannot be processed?

• Can you reproduce the issue by creating new documents? (Using a sandbox, step 3)

Step

7: Reproduce the issue in a "Sandbox" (copy of the production)

With a sandbox you can:

• Avoid disrupting the customer's business

• Change data to check whether the issue changes

• Disable/Enable extensions and check if issue changes

• Debug code

• Debugging

Step

8: Troubleshoot

performance using Profiler

See Performance Profiler (AL Profiler)

Also, when dealing with slow performance on BC Online, consider raising a Support Case with Microsoft, directly from Business Central.
