This FM first extract the field list from the I_DDIC_NAM dictionary structure.

Then it compare the two data structure I_REC_OLD and I_REC_NEW for each field of the DDIC that exists on both structure.

If I_CHECK_MODE equal 'X' it stop at the first changed field, else it compare every common fields of the two structure parameters.

Sample

DATA field1 TYPE mara,
     field2 type marc,
     is_diff.
* compare
CALL FUNCTION 'COMPARE_STRUCTURE_DATA'
     EXPORTING
          i_ddic_name  = 'MARA'
          i_rec_old    = field1
          i_rec_new    = field2
          i_check_mode = 'Y'
     IMPORTING
          e_is_diff    = is_diff.

The FM will compare each subfield of field2 (structure MARC) and field1 (structure MARA) that exists in database MARA and MARC, if any field value differs, it will return is_diff = 'X'.
