Hi,
I wanted to know if there is any way in which we can enable offline approvals of work items in ECC 6.0.where offline means user need not login into sap system for approval.
An ideal scenario would be that a user recieves an email with Approve/Reject option, and on clicking any of these options, the necessary updates are registered by the SAP system. So is it possible to implement the above by making use of WebServices or something else?
I have searched on forum and could see blog for offline approval through outlook but our requirement is - user want to approve workflow through webmail/phone .
Any help or guidance will be very helpful and rewarded 
Thanks,
Ajit
