Determining transaction code in the workflow runtime

Hi Experts,

I have the requirements where when document created in the transaction code FV50 and FV60

document has go to approver to release document.

For both transaction event CREATED(Business Object FIPP) is triggering. Workflow working perfectly.

Now user has come requirement when tcode FV50, it has to go for one releaser and FV60 it has to

go for other user for realise.

As i dont know in runtime whether we get the transaction code, how we can achive this?

Regards,
