payslip creation how we can get wagetypes on payslip

Hi to all

My client wants his own payslip means..he wants address of the company on top of the page (this is done by abap ers)

under address he wants name of an employee, location,PF number amd ESI number (these abap ers can get through transparent table,,clearly for ex. for PF in INF 587 put the cursor PF number field..press F1, >Technical settings. >field name EEPFN ->IT GIVES STRUCTURE ->then click on where used list

finally it gives the transparent table name and all then ABAP'r can do

Under this one side earnigs and another deductions.

earning side these componets should appear.

BASIC

HRA

CCA

CONVEYANCE

These are inf 8 components

if we try as i said above for these field in info type 8 we can get so many components (wage types) with some other naming format..among those i am not able to find which one belongs to BASIC,HRA or Something else.

My question is how we can get for this components?

One of my friend said that they are stored in clusters. IF IT IS how i can see or say to ABAP"

cluster and all

Thanks in advance
