Failing to create Tablix



I am trying to create a tablix through aspose cells SSRS but getting an error on publish:

Details: The element ‘TablixColumns’ in namespace ‘’ has incomplete content. List of possible elements expected: ‘TablixColumn’ in namespace ‘’ as well as any element in namespace ‘##other’.

I am following the instructions steps by step but it is not working.

I have attached the file generated by Aspose and the same file generated by SSRS with a functioning tablix.

Could you let me know what I should change in Aspose for it to function?

just to let you know that based on another user that had the same issue The definition of this report is not valid or supported

I tried to follow your suggestion of adding a ##header flag but it does not change the error.

it does seem to be linked to the row group as if I use the normal code (without group) the error changes:

invalid TablixCornerCell. The CellContents for this TablixCornerCell is required if not covered by a span from another TablixCornerCell.

I really cannot fathom what else I could try since it really seems to be a matter of having 2 groups, 1 sum and setting the attributes to englobe all 4 cells.
