check function module in 40B

[Almeida Viraj]

Hi friends,
I use a check FM for a workflow.
After event "PR created" is triggered, I check document type of PR.
For certain Doc Type of PR  Workflow should be started.
 
the event container gives Pr number.I use the number to find PR doc type
from EBAN.
But doc type is not returned...it gives me empty string.
 
wot could be wrong?
 
Alttough it works fine during Explicit Generate Event tool..
 
thanks in Advance,
 
Viraj
