Non zero return code from macro swc_get_property

[Michael Arter]

Hi,
We have a background task that is executing as the first step in a
workflow.  The background
task is executing an object method which executes the macro statement
SWC_GET_PROPERTY
to retrieve some object attributes.
 
Our problem is that one of the "get property" macro's is returning a subrc
of 8 (when running
within the workflow instance),  while the others are returning zero's.
 
What is frustrating is that when I test the object method using the same
object data as the workflow
instance, ALL the return codes are zero.  The data type references for the
object attribute and
the object method variable are exactly the same - ie. referring to the same
data dictionary field.
 
Is there a way I can trap the execution of the background task within a
debug session to try and
determine why the macro call is failing????
 
 
NB:
 
1.  I've tried using the test w/flow tool in conjunction with the debugger
setting "In background task: Do not process"
but unfortunately the resulting transactional RFC only seems to capture the
initial call to the workflow internal rfc connection
and not the execution of the background task by WF-BATCH.
 
 
2.  As per the code below, 3 of the attributes are inherited from the
supertype standard
business object - 'Currency', 'TotalValue' & 'Plant'.  The retrieval of
'Currency' & 'Plant'
works but 'TotalValue' is failing.  The retrieval of all sub type
attributes are correctly
working.
