Assign fields

[Former Member]

Hello everybody.

First of all, sorry for my English, I am from Catalonian and I know my english is very poor.

Ok, I am developping in Abap since 6 months, more or less, and know I have a little problem.

I hace defined an internal table where there are 12 fields like these: quantity01, quantity02, ... quantity12. Every field is defined for every month (January, february, ... , december).

My idea is assign the values depending of a date contained in other field of the table (field period).

Is something like this:

LOOP gt_report into gs_report.

  IF gs_report-period = '01'.

    gs_report-quantity01 = gs_report-quant.

  ENDIF.

.......

  IF gs_report-period = '02'.

    gs_report-quantity02 = gs_report-quant.

  ENDIF.

ENDLOOP.

I don't want to work with 12 IF's, because I have to do other operations.

I supose this is very easy for most of you, but I have searched a lot and I didn't find anything. I heart something like fieldsymbols but I don't know if these is really the solution.

Can anyone help me, please?

Thank you in advance.

Hi Marius Conchillo,

I am not having much expertise in the abap so i think my reply may help you.

I understood that your code should not write more if....endif statements.

Instead of writing multiple if...endif statements, we can assign the values to a data object and write a case statement.

using case..... endcase we can exclude multiple if statements.

I think this helped you.

Thank you for your answer Harsha.

Ok, I can use case/endcase, but by this way is more or less the same. Finally, I have to write 12 portions of code (1 for every month).

The idea is write only one.

Thank you Harsha.

Hello Conchilo,

You can try like this.

DATA : V_PERIO(40) TYPE C,

             v_fs type any.

LOOP at gt_report into gs_report.

concatenate 'GS_REPORT-QUANTITY'  GS_REPORT-PERIOD INTO V_PERIO.

ASSIGN (V_PERIO) TO V_FS.

V_FS = GS_REPORT-QUANTITY.

ENDLOOP.

Hi,

This will not work

here is how it should be

You can try like this.

DATA : V_PERIO(40) TYPE C.

FIELD-SYMBOLS <fs> TYPE ANY

LOOP at gt_report into gs_report.

concatenate 'GS_REPORT-QUANTITY'  GS_REPORT-PERIOD INTO V_PERIO.

ASSIGN (V_PERIO) TO <FS>.

IF <FS> is assigned.

<FS> = GS_REPORT-QUANTITY.

ENDIF.

ENDLOOP.

Gourav.

Hi Yakub,

By mistake I wrote that line.

<fs> type any within data,Yes it will under field-symbol.

Hi Marius,

Other similar way to solve the  problem is:

DATA: lv_name TYPE string.
FIELD-SYMBOLS: <lv_content> TYPE ANY.

LOOP AT gt_report INTO gs_report.
  CONCATENATE 'QUANTITY' gs_report-period INTO lv_name.
  ASSIGN COMPONENT lv_name OF STRUCTURE gs_report TO <lv_content>.

  IF <lv_content> IS ASSIGNED.
      <lv_content> = gs_report-quant.
  ENDIF.

  CLEAR: lv_name.
  UNASSIGN: <lv_content>.
ENDLOOP. 

Hope it helps. Cheers!
