EPM Error "Internal Server Error" on Refresh .

Helllo,

          I have this strange error on an input Schedule. This one tab gives an error "Internal Server Error" on Refresh Worksheet or Workbook. This is a new environment, The same Input Schedule works just fine in another environment which is very similar to this.

The error is not very clear and I am not sure where to start debugging.

Please help.

Thank You,

Indu
