Trouble with TABULATE using CLASSDATA=

[danthomas25]

Hi, I followed the "plan" as per SAS 9 documentation, yet for a tabulate that used to output 1000s of rows, it now just selects 1 row and generates no output table.
TABULATE statement is like this: "PROC TABULATE data=dan.dec07tomar08_final_IH noseps f=comma16. out=MGStab classdata=dan.MGSquery_classes exclusive;"
The classdata dataset contains all required combos of class variables I want output, but nothing is selected. 2 of my 3 class vars are character, could this be a problem? I use printmiss on the table statement - but removing this had no effect, so I suspect this is OK.
Any thoughts? further info reqd? Thanks all.

A further thought - might it be because my classdata dataset is a superset of classes in the main dataset (rather than a subset) ??
