do...varying... with variable starting point 'from'

[Former Member]

Hi together,

I want to use 'do...varying...' in order to add special columns (e.g. hsl03 to hsl10 of tabel faglfext).

The problem is that the starting point ( hsl03) is set variably:

DO x TIMES VARYING i_sum FROM faglflext-hslxx NEXT 'faglflext-hslxx + 1'

Thanks for any help

The 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

ld_auf0x

ld_psp0x.

APPEND output_tab.

ENDDO.

Hi,

I know, how it works in general.

If you look at your exaple:

DO 21 TIMES VARYING ld_p0121 FROM p0121-RFP01 NEXT p0121-RFP02.

My problem is that position/fieldname p0121-RFP01 is 'unknown' because it is set dynamically by entering the

starting period on the selection dynpro of the report.

e.g. you want to calculate the sum of faglflext-hsl02 to faglflext-hsl06.

Therefore you put period 2 ...to 6 into the according parameter fields.

In this case the coding would be like:

do 5 times varying i_sum from faglflext-hsl02 next faglflext-hsl03.

i_total = i_total + i_sum.

Hi,

Thanks for your help.

Gues I´ve resolved the puzzle.
