Solved
Even though the element has been mapped , TC still popup dialog '..because it is not mapped..'.
As the subject title said, I have already mapped the element into the NameMapping.
But when I clicked 'Show object in Name Mapping Editor', the error dialog displayed.
Like the capture:
Whether there are some limits in name mapping? Or it is a bug.
Tips:
1.This situation only happened after I editor mapped object in Name Mapping.
2.Current version is 14.70.237.7.
Please check my upload video Normal and Exception in detail.
You can use different sheets in the same spreadsheet for different scenarios. There's an example in here for getting to a sheet by its name.
