exception in class and passing of parameters

[Mike Gambier]

Jocelyn,

 

I'm not sure that's entirely accurate anymore. ABAP was adjusted some time ago to return EXPORTING, TABLES and CHANGING parameters in FMs or ABAP Class Methods even if you raise an exception.

 

We have several examples of where an Exception is thrown and we can still trust the value of an Exporting 'Error' flag or Application Log instance as well.

 

The flaw highlighted by Robert I think is buried in the way the value being received is being bound (or not) into the Method container.

Hi Robert, 
 
If you raise an exception, the exporting parameters are NOT returned to the calling application (not just workflow – all calling applications)  – exact same behaviour as function modules.  The test tool “cheats” a little.  
 
So for a synchronous task either use an additional exporting parameter to indicate success/failure or use an exception class to update the workflow log with your returned value.
Or raise an event (with or without parameters) – and make your task asynchronous.

Hi Group,

 

I have a task which uses a method of a class. This method has export parameters and exceptions.

Before the exception is raised, the export parameter is set.

 

The problem is that, when the exception is raised, the export parameter is empty. When I test the method from the class builder, the export parameter contains a value but when I test the workflow, the workflow container is empty.

 

Does anyone have an idea?

 

Regards,

Robert
