Wrong type of format for data type

[draroda]

There is no issue in it as it is working on SASHELP.CLASS data.

I have taken it from here.

And did you try putting Other in the format declaration as given in that post you refer me to, I don't see it in the code you post here and they specifically talk about that error and provide a possible workaround.

What can we say, no test data, no code, no required output, no log, nothing.  All we have here is:

Wrong type of format

So, my response is, correct the format.  I don't see how you would "apply a format" to a spanned header, spanned headers in proc report - if indeed that is what you ues - forms:

columns("Some text to put across values" <variable> <variable>);
define <variable> / "Label for the variable" format=...;
