Hi Vishnu,
Try below.
Check the workflow execution user name
Go to user form and then find the workflow execution user and open the options form for it to check whether you will get any error.
Also edit and save the the user on a user form to confirm that AX validates the the user correctly.
Once above is checked then go to batch job forms and delete all three workflow batch jobs.
Go to workflow wizard and regenerate these workflow jobs.
Change the batch jobs history paramter to save for all.
Set to run batch jobs every 1 minute.
Check the history for each batch job whether there are ending succeffully.
It should work for you then.
Regards,
Nadeem
