Passing internal table field dynamically in a LOOP

stefan_kolev4 — Tue, 12 Jun 2012 11:03:32 GMT

Hi All,

I have an interanl table ( gt_table ) which records are as follows:

fldname|spos|epos

fld1 0 10

fld2 10 15

fld3 15 12

Of course this is an example

I need to pass an internal table field dynamically to the work area that I will append to other internal table.

For example:

LOOP AT gt_table INTO wa_table.

wa_final_table-<dynamic field> = wa_table-value.

APPEND wa_final_table TO gt_final_table.

ENDLOOP.

In the above example <dynamic_field> wil be wa_table-fldname.

How can I pass/assign that fieldname to the structure wa_final_table ?

Please advise !

Thanks,

Stefan

Hi Stefan,

Use this.

field-symbols : <final_value> TYPE any,

<wa_final> TYPE wa.

LOOP AT gt_table INTO wa_table.

ASSIGN COMPONENT "FIELDNAME" OF STRUCTURE <wa_final> to <final_value>.

<final_value> = wa_table-value.

APPEND <wa_final> TO gt_final_table.

ENDLOOP

Thanks,

Shambu

Replace

wa_final_table-<dynamic field> = wa_table-value.

with

ASSIGN COMPONENT fieldname OF STRUCTURE wa_final_table TO <fs>.
<fs> = wa_table-value.

Raymond

Thanks Shambu !

It is not enough clear

Let me clarify.

I have an int.table and it has the following structure and records

fldname|spos|epos

fld1 0 10

fld2 10 15

fld3 15 12

I am trying to achive at run-time the following:

LOOP AT gt_table INTO wa_table.

* on first record

wa_final_table-fld1 = wa_table-spos.

* on second record

wa_final_table-fld2 = wa_table-spos

* on the thitd record

wa_final_table-fld3 = wa_table-value..

APPEND wa_final_table TO gt_final_table.

ENDLOOP.

Can you please explain more with an example ?

Thanks in advance !

Stefan

Hi,

use the Field symbol for dynamic data passing.

Write code in this way...

Loop at gt_table into wa_table.

move corresponding wa_table to wa_final_table.

append wa_final_table to gt_final.

endloop.

Still the requirement is not clear.

LOOP AT gt_table INTO wa_table.

ASSIGN COMPONENT wa_table-fldname OF STRUCTURE <wa_final> to <final_value>.

IF sy-subrc = 0.

<final_value> = wa_table-spos.

endif.

APPEND <wa_final> TO gt_final_table.

ENDLOOP

Is this what you want?

Thanks,

Shambu

Hi Stefan,

Not geeting your requirment,,,,,,,,,,,,may be this will help,,,,,,

field-symbols : <final_value> TYPE any,

<wa_final> TYPE wa.

LOOP AT gt_table INTO wa_table.

ASSIGN COMPONENT sy-tabix OF STRUCTURE wa_table to <final_value>. "for field1

wa_final-field1 = <final_value> .

ASSIGN COMPONENT sy-tabix + 1 OF STRUCTURE wa_table to <final_value>.

wa_final-field2 = <final_value>.

APPEND <wa_final> TO gt_final_table.

ENDLOOP

Thanks,
