Get the value dynamically from internal table

[Former Member]

Hello expert,

I have one strcture defined which has fields =    field01, field02 , field03, field04, field05, ..... field100

Data:  ls_field type <structure type>

           lt_field type table of ls_field.

data: lv_fieldName  type string.  //   hold the value of field name ..  field01  or field02 or field03 or ..... field100

I am passing 01, 02, 03 .... as input

so my lv_fieldname will be    =    field01 or field02 or field03.

for exaple,  lv_fieldName =  'field02'.

Now,  I am looping table lt_field. which is populated.

Loop lt_field into ls_field.

write  ls_field-lv_fieldName .

//  program is giving error at this point... my question is , i want to get the value dynamically based on string ( lv_fieldName) but lv_fieldName is not part of the structure. so its giving me error.....

Correct way is    write ls_field-field01.    // can we reference the field name dynamically to get th values.

endLoop.

Assign Component of Structure statement can be used.

Look at this snippet.

TYPES:
BEGIN OF ty_test,
   field01 TYPE char10,
   field02 TYPE char10,
END OF ty_test.
DATA: ls_test TYPE ty_test,
       lv_varname TYPE string.
FIELD-SYMBOLS: <fs>.

ls_test-field01 = 1.
ls_test-field02 = 2.

lv_varname = 'FIELD02'.
ASSIGN COMPONENT lv_varname OF STRUCTURE ls_test TO <fs>.
IF sy-subrc EQ 0.
   WRITE:/ <fs>.
ENDIF.
