The function entered gives the same output for all inputs. This may result from adding the capability to do non-linear adjustment of inputs that ended up not needing adjustment. There may also be examples where the function has a very low non-zero slope (for example related to monitoring equipment life). Flat functions identified by DBDOC with this message have a slope of less the 1E-10.
