For example if we have a Date type variable in our bean class and we configured an eWorksheet by changing the data type from date variable to timestamp.
While opening eWorksheet if we query on same variable.
It will raise an exception.
This happens when there is a mismatch of data type in bean class and configuration.
Verify the Generated bean class
eWorksheets – Premium --> Workbench --> Functions --> Generate Business Objects
Select the bean class and check the variable data type.
Viewer configuration :
In the configuration check the data type of the column.
To avoid exception in both palces data type must be same.
