Hi @rebeca.padil12,

It sounds like your OLAP table contains characters that have a special meaning in the Excel File. An Excel file is in XML, which contains a lot of '>' and '<' signs. Also the backslash '\\' has a special function often. Based on your error code, do you have any of this signs in the table?

Kind regards,

Hi, just to let you know the issue and solution

In my Dimension I had a variable, that inside the variable had another variable... This is the reason of the error message

Solution: I had to change the second variable for a direct constant
