concatentation - allowable characters

[ry1633]

Are there certain allowable characters in a Cognos concatenation for a query subject or item?   I'm trying to do reference number concat of a few different collumns:  Part, Section, and Subsection that would be like this:

Example:  110.2(a)
•   part=110
•   section=2
•   subsection1=a

But Cognos seems to not like the parentheses.

[PART] || '.' || [SECTION] || '(' || [SUBSECTION1] || ')' ||

[bus_pass_man]

Telling us the error message might be helpful.

My first guess is that it is complaining about the data types  of the query items which you are trying to concatenate. 

You might need to cast the numeric data type query items into strings.

Well,  FM wouldn't ever give me a specific error message beyond just a parsing error with no notes.    I thought it was the paratheses,  but I think it was the order of the close || marks

I think the two || symbols at the end would cause a parsing error because it is a concatenation operator but you don't have anything specified after that to concatenate. Of course the data type is also important as bus pass man explained.
