Unable to find any value in Column Attribute LOV while defining Global Data Element segment in DFF

If you are unable to find any value in Column LOV while defining segment for “Global Data Element” in DFF. It means you have already utilized all attributes in other contexts. You need to remove those attributes from all contexts to make it available for "Global Data Element".

Same Attributes can be used in multiple contexts but you cannot use those attributes in "Global data element" if already used in any context.
