Hi @S G ,
The "Add Total" command is context-sensitive and only supports numeric fields. You can refer to: Add totals to a group or Tablix data area (Report Builder and SSRS)
I did some tests as follows.
Then I click on the "Salary" option to add the total.This operation can be successfully performed.
This is the sum of the grouping "Hire Date". The preview effect is as follows.
Right click on the "Sun(Salary)" option to add the total.This is the sum of the grouping "Department Name".
In the end we will get the result as shown below.
Regards,
Joy
