Cannot insert a members, Input schedule protected sheet.

Hi all,

After to build an input schedule and protect the sheet I’m not able to use the functionality (Right click/EPM/Insert Members) to insert a new member,  after to do these steps I get the following error: 

No member insertion filter has been created for the dimension. You cannot insert any member.

But if have don’t have the sheet protected, it works fine and I can insert members, I´m using the EPM Add-in 10 SP 13 Patch 5. I saw in some discussion that the patch 5 corrected this issue but not in my case.

If you have some ideas to make works the member insertion using the sheet protection I will be grateful.

Thanks
