"(MXCGPUT02) You cannot assign values to SURROGATE %n because it is type INTEGER."
*Cause: The user attempted to assign a value to a dimension surrogate whose
data type is INTEGER. INTEGER surrogates, like INTEGER dimensions, cannot
have values assigned to them. They can only be referenced by position.
*Action: Do not attempt to assign values to an INTEGER surrogate. Values
will automatically appear and disappear from the INTEGER surrogate as
positions are added to or removed from the underlying dimension.
