Regarding ALV format

Question

Dear All:
i want to generate a withholding tax report with following format. i populated two internal tables for vendor information and withholding tax information. but cannot bring the format like this:
Vendor      10000012     Vendor Name     ABC Traders          
Document No      Document Date     Posting Date     Withholding Tax Code     Withholding Tax Base Amount     Withholding Tax Amount
50000010     12.06.2010     12.06.2010     A2     10000     100
50000011     17.06.2010     17.06.2010     A5     42500     425
50000012     28.06.2010     28.06.2010     A5     81569     815.69
can anyone help me how i can generate this format? can anyone provide me any sample code for that?

Hi
Generally the order of fields in the alv report is same as that of the internal table.If you want to have your specific order then you need to make your own field catalog.
Sample code:
FORM BUILD_FIELDCATALOG.
     WA_FIELDCATALOG-TABNAME = 'Y78EMP'.
     WA_FIELDCATALOG-FIELDNAME = 'EMP_ID'.
     WA_FIELDCATALOG-COL_POS = '1'.
     APPEND  WA_FIELDCATALOG TO FIELDCATALOG.
    CLEAR FIELDCATALOG.
     WA_FIELDCATALOG-FIELDNAME = 'LAST_NAME'.
     WA_FIELDCATALOG-COL_POS = '2'.
     APPEND  WA_FIELDCATALOG TO FIELDCATALOG.
    CLEAR FIELDCATALOG.
     WA_FIELDCATALOG-FIELDNAME = 'FIRST_NAME'.
     WA_FIELDCATALOG-COL_POS = '3'.
     APPEND  WA_FIELDCATALOG TO FIELDCATALOG.
    CLEAR WA_FIELDCATALOG.
ENDFORM.
Col_pos parameter of the fiield catalog gives the column position.
And you need to pass the this field catalog name in the IT_FIELDCAT parameter of REUSE_ALV_GRID_DISPLAY
Thanks!!
