Is 'ABAP HR' two separate modules ? do i need to learn ABAP & HR modules seperately ? what is the scope of 'ABAP HR'

Hi Fahrukh, As stated by @Neeraj Gupta, There is less of comparison between ABAP and HR ABAP, but if you are keen to learn SAP HR that is possible separately only. There are several institutes in the country which are offering SAP HR / other modules, you may refer to the following link : tinyurl.c

There is nothing much difference between abap and hr abap In general ABAP data is stored in Tables, but coming to HR ABAP employee data is sorted through Infotypes. The way we retrieve the data from infotypes is deferent in hr abap. if you want to go in details then you have to learn HR seperatly
