Hi Das,
You can not hire employee with T-code : Pa30 (Maintain HR Master data)use pa40 (personnel Actions) or pa42 - (fast entry for actions) to hire employee.
In the standard system, different types of employee data are stored in individual infotypes. Rather than accessing each infotype individually and entering data into them, the system can group together the most important infotypes into personnel actions and lead you through processing the employee data.
Personnel actions
Personnel procedures, such as hiring an employee, organizational reassignment, or an employee leaving the enterprise are represented by individual personnel actions in Personnel Administration. Each personnel action contains the infotypes that you must maintain to record the personnel action at hand. The infotypes are retrieved in succession so that you can maintain them. For example, all the fields in which you need to make entries to hire an employee will be offered to you for maintenance automatically by the system in the personnel action Hiring.
This ensures that all the core data is entered into the system. This function also facilitates entering data as you do not need to access each infotype within the personnel action individually.
Customizing enables you to adapt the Hiring personnel action type so that it meets your enterprise’s exact requirements.
