Work flow Issue - 2012

Hi All,

i created purchase requisition work flow in 2012 for only one particular user. the user got purchase requisition details but user could not able to approve the PR. b’coz the approve button is invisible in Action button. i tried with different options like user, user group and workflow user and all. still am facing the same issue. could any one please help me out on this issue, Where i went Wrong.

Thanks in Advance,

Regards,
