Custom Travel WorkFlow : Error Database error '4' reading table 'SWD_HEADER

Hello,

I have created a Rule : 90000007 when tested/simulated, works Fine.

When i test the workflow with an Instance returned from SWUE

again it works fine.

But when tested through transaction TRIP, results in error in the rule : Database error '4' reading table 'SWD_HEADER'

Checked SWU3, plan version has been generated, also in table SWD_HEADER, the active version of the workflow entry has been seen.

Please advise.

Regards,

Remi
