Hello
The data for different actions related to an employee would be different and hence the infotypes will also differ.
If you have an action to update Employee Qualifications only infotypes related to Qualification need to be used. If the action is to do with pay change only the infotypes like 008 and 007 related to salary come into picutre.
Refer to this blog PA40 - Actions Configuration by Bhagyashree Naik
Hope this helps.

Sahir.
