The analyzer identified a compatibility issue with a tool parameter.
A parameter's filter list (or domain) limits potential parameter values.
A change in the filter list means values were added or removed from the list. For example, a parameter with a dataType value of feature class may also have a filterList value of Point, which may change to Point or Polygon.
The parameter filterList value is not consistent at the current version and the selected target version.
Use the target version of the software to review the processes in model and script tools that were identified with compatibility issues. Review the version-appropriate tool documentation, run the model or script tool, and review the output to confirm it is acceptable.
