Can't save and update
I Install Epm Add in in my server
But user can't save or update
Check few things,
1) Check that your input template is not protected.
2) If it is protected then first unlock it then only edit options will enable for you. Do your changes and then again lock.
3) If you input template is not protected then check task profile which is assigned to user and he has access to edit existing reports/ Input schedules.
4) If he has access to edit reports and Input schedules then Kindly check that is there are any microsoft updates are installed (KB2553154). If theseupdates are installed then try to uninstall the Microsoft update "Security update and restart your PC.
Also go through below links.
5) Once edit report is enable for you then also you can use report specific options then Go to edit option and check report specific option. Unchecke Inherit sheet options and do check mark use input form
Hope this will solve your problem.
