A few years back, I was presented with a difficult dilemma - restricting multiple numeric ranges, dependant with character values. Normally, if it's simple enough you can just use constraints & "if statements" to get what you need - but this was really complicated - full of "or's, and's, in's and not's".
Out of the box SAP is no help to this. It doesn't support direct ranges (1-10) and specifying out 10 lines of nearly identical data is a maintenance nightmare.
