PAYROLL EXPENSING PROGRAM

I have a requirement like this:

I have to download the payroll expensing data in such a way that it contains PERNR , LGART (Wage Type) , BETRG (Amount) , GL A/C and PROJK (WBS Element) as fields!!!! One serious issue is my client has requirement like, he has one GL A/C mapped to different Wage types (for ex: LTA arrears and LTA are mapped to same GL A/C). Is there any table which will contain all these details as in the manner explained above? BSEG doesn't contain the LGART field as it contains only the summarised data of Payroll results excluding the LGART.
