Anubhav,
lf 0TCAKYFNM is marked authorization relevant then you should be able to able to use range values to exclude the salary key figure (i think it is 0ANSALARY). Excluded operator is not valid for 0TCAKYFNM , it is valid for only 0TCAVALID so you will not be able to use it to exclude a value. Like the rest of SAP fields, you will have to maintain a range for exclusions.
