Can't save in My Favorites

hi,

I have this problem: users can't save workbooks in their own My favorites? this is just hapenging a few days ago.

When a users try to save a New Workbook, the system responds with 2 messages:

"Document store access caused error in the SAP Correction System"

and then

"the workbook was not saved"

Why is this happening??

what shoiuld I do to correct this, and let the users create their workboos in their My Favorites???

regards,

Mauricio.
