Header report

Hi,
You can find the Report headings in language file components/com_vaccount/language/en-GB folder
Queries can be found in Dashboard model to fetch the records in reports components/com_vaccount/models folder

Salary can be entered in Employee section in backend.

Hi, how can I change the name of the heading at diferent reports, and I don´t want all the records, where can I modify the report??

Also I need to know the salary for each employee for the expense.
