Assign component in loop

Former Member — Tue, 23 Nov 2010 18:31:52 GMT

HI All

I doing the following loop and the table it_mapping can be with lot of records

There is a way that i can do the loop for just the relevant field (something that similar to LOOP and Where )

since for instance table ls_mapping can be with 10000 records and in structure <ls_attributes> i have just

2 fields that are the same (the loop run dynamically since <ls_attributes> can be differnt in every run of the program )

LOOP AT it_mapping INTO ls_mapping.

    ASSIGN COMPONENT ls_mapping-target_field OF STRUCTURE <ls_attributes>

    TO <lo_attr>.

    IF sy-subrc = 0.

      <lo_attr> = ls_mapping-field_value.

    ENDIF.

  ENDLOOP.

Regards

Alex

<ls_attributes> can be different, but it_mapping seems to be a normal internal table, so why don't you do:

LOOP AT it_mapping INTO ls_mapping where ......................

Yes I know it

But the structure of it_mapping is constant, probably its values can be different

Hi friend,

here ls_mapping contains fields same fields are available to <ls_attributes> fieldsymbol

then only when pass the value to <lo_attr> then automattically value comes then u can insert into the internal table that must declare as fieldsymbol.

TYPES:BEGIN OF TY_MAPPING,

FLD1 TYPE STRING,

VAL TYPE STRING,

END OF TY_MAPPING.

DATA:LS_MAPPING TYPE TY_MAPPING,

IT_MAPPING TYPE STANDARD TABLE OF TY_MAPPING.

FIELD-SYMBOLS:<LT_ATTRIBUTES> TYPE STANDARD TYPE OF (LS_MAPPING).

ASSIGN LT_ATTRIBUTES ->* <LS_ATTRIBUTES>.

LOOP AT it_mapping INTO ls_mapping.

ASSIGN COMPONENT ls_mapping-target_field OF STRUCTURE <ls_attributes>

TO <lo_attr>.

IF sy-subrc = 0.

<lo_attr> = ls_mapping-field_value.

APPEND <LS_ATTRIBUTES> TO <LT_ATTRIBUTES>.

ENDIF.

ENDLOOP.

I think it will be excuted.

thanks&regards.
