In my workflow, I have created one activity for reason for rejection and I am using task(TS20000139) for sending short message with reason and in binding I am passing wofkflow initiator(&_WF_INITIATOR&) to receiver(&RECEIVER&). But the problem is workflow initiator is not pickingup exact user name. If the username is 'STEVE' it is picking 'USSTEVE', because of this it is showing an error that user does not exists. If I remove that 'US' my problem will get solved. Plz suggest me.
