Hi All,
I have a scenario for an assignment.
Consider the following sample data,
| Roll Number | Subject | Amount | Error |
| 1011 | Fee Installment | 23122 | |
| 1011 | Fee Installment | 12312 | |
| 1012 | Fee Installment 2 | 23215 | |
| 1012 | Fee Installment 2 | 23215 | |
| 1012 | Fee Installment 2 | 23512 | |
Condition:-
For a particular Roll number(column1) for same subject(column2) amount should not be same.
If same amount is encountered for same subject type then error is thrown in an another column name error otherwise success.
