Getting Error while running the paginated report in report builder

[Pawan_123]

The 'Hidden' expression for the grouping 'DayOfMonth' refers to the field 'Date_Day_Of_Month'.  Report item expressions can only refer to fields within the current dataset scope or, if inside an aggregate, the specified dataset scope. Letters in the names of fields must use the correct case.

The definition of the report '' is invalid.

An error occurred during local report processing.

Hi, @Pawan_123 

You need to make sure that the field name is spelled correctly and that the case exactly matches the name that appears in the dataset. Field names are case-sensitive. Also verify that the field 'Date_Day_Of_Month' is within the current dataset range. You can check the following link:
