VARYING command - Example ABAP code to demonstrate the VARYING command
The SAP / ABAP varying command is a function of the DO loop which allows you to move horizontaly along a table row without actually having to specify each individual field name. i.e. if the table row had the fields: Field1 Field2 Field3 Field4 etc you would be able to loop around each field using only one DO..VARYING command.
*Code to demonstrate VARYING command
* The varying comand works on the position within the row, therfore
* each field must be the same number of fields apart.
DATA: ld_p0121 type p0121-rfp01,
ld_numcont type i.
DO 21 TIMES VARYING ld_p0121 FROM p0121-RFP01 NEXT p0121-RFP02.
IF not ld_p0121 IS INITIAL.
ld_numcont = ld_numcont + 1.
ENDIF.
ENDDO.
*Code to demonstrate multiple field VARYING command
DATA: ld_kst0x LIKE p0027-kst02,
ld_auf0x LIKE p0027-auf02,
ld_psp0x LIKE p0027-psp02.
DO 25 TIMES VARYING ld_kst0x FROM p0027-kst02 NEXT p0027-kst03
VARYING ld_auf0x FROM p0027-auf02 NEXT p0027-auf03
VARYING ld_psp0x FROM p0027-psp02 NEXT p0027-psp03.
PERFORM get_cost_center_and_text USING ld_kst0x

APPEND output_tab.
