Did you read the error explanation in the first image?

"no method has been selected" is a quite good description…

method will be selectable if I select a class in the following way. but it caused many report generator VIs having error. Now, I don't know how to recover these report generator VIs. really bad!

I can easily recreate the code from your first message (LV2016, 32bit, Office365):

I just dropped the 3 RGT functions and an invoke node: no problems to select a method, no problems with RGT functions after selecting the method…

So the problem seems to be with your specific computer/software installations!

I think we need to know a little about your software versions

Looks like you are using office in a 64-bit version. 

Is your LabVIEW in 64-bit version? 

[DavidWei]

a good question!

my office is 64-bit version. while Labview is 32-bit version due to Labview 64-version doesn't support Database connectivity. maybe this is the cause.
