For example:
Add a table to the report, and insert a data field.
Double click on the report item will popup the dialog “Edit Data Binding”.
Click the fx… icon of the “Expression:” textbox.
There are 3 textarea below:
Category, Sub-Category, Double Click to Insert.
There are some items in the Category:
Available Data Sets, Available Column Binding, Report Parameters,
Native Javascript Functions, Reporting Functions, Operators
Select “Reporting Functions” in the Category, the Sub-Category is always empty.
I remembered that it should have “Finance Function” etc. options in the 7.0 M2.
Now it’s all gone, just empty.
