How to append records filtered be vbrp-pstyv & konv-kschl

Hi,

I am working on requirement for pricing report .

I have to fetch records from vbrp & pass it in konv to get the konv-kbetr.

My condition would be :

if vbrp-pstyv = 'TAN' or 'zts1' or 'ren'      ----->  then pick konv-kbetr which has kschl = 'vprs'

        "            "  'ZTAC' or 'ztab'                                  "                                         "          'EK02'

       "                'TAX' or 'ztad' or 'ztax'                        "                                        "           'Z004'

I am trying to fetch records based on conditions but the problem is my records from konv table are overwritten & only last record is displayed.

Below is query :

Is there any other way to do this report as I have no idea how SD PRICING works ?? Please advice.
