WM RF screen error - Failed to call screen

[former_member188800]

Hi Guys,

I had developed a custom screen for LM05 picking transaction by copying a standard screen. The custom screen has also been defined in screen management with user exits activated. The custom screen also displays in LM05.

The problem is sometimes after the custom screen is displayed i get a error message saying "Failed to call screen". The same if it is executed without custom screen it shows the next screen and the process continues.

What could be the problem? Please let me know.

Thanks in advance

This is a Standard Message type "LF 109", you can easily search where the Message is raised, possibly by using a WatchPoint through Debugging for the specific Message when executing the Transaction ...

I you created the Custom Screen, you should see it as your own responsibility to find out when and why the Message is often / always raised ...

Using the Message-ID and Number in combination with a Watchpoint should get you more insight.

Hope this helps

Hi Nic,

Thanks for the reply. Debugged the same and found that my custom field label was considered as field while processing.

Changed the current field from user exit and it worked.
