Help with respect data transfer between two structures

[Former Member]

Hi,

How can we move data between two structures which are similar using one command without overwriting the data in the target structure?

Example :- Structure A and Structure B are similar in type with 5 fields each. A has data in fields 1 & 2. Where as B has data in 4 & 5. Now I need to transfer the data of fields 1 & 2 of structure A into 1 & 2 of Structure B without disturbing the values in 3,4 & 5 fields of Structure B.

How can we make it? Requesting your suggestions.

Regards,

Sanjeev

Assuming structure 1 name  = wa_stru1.

structure 2 name = wa_stru2. and both structure have the same type

do the following code

 FIELD-SYMBOLS : <fs_any1> TYPE ANY,
                 <fs_any2> TYPE ANY.
  DO.
    ASSIGN COMPONENT sy-index OF STRUCTURE wa_stru1
    TO <fs_any1>.
    IF sy-subrc NE 0.
      EXIT.
    ENDIF.
    IF <fs_any1> IS NOT INITIAL.
      ASSIGN COMPONENT sy-index OF STRUCTURE wa_stru2 TO <fs_any2>.
      IF sy-subrc = 0 AND <fs_any2> IS INITIAL.
        <fs_any2> =  <fs_any1>.
      ENDIF.
    ENDIF.
  ENDDO.

Hi Sanjeeva,

As far as i know it isn't possible to make that assignation with only one instruction.

You could use an CASE/IF for each substructure or to use field symbols.

You could introduce a structure C with just the fields 1 & 2 and then

MOVE-CORRESPONDING structureA to structureC.

MOVE-CORRESPONDING structureC to structureB.

Don't limit yourself to artificial "with one command" restrictions, unless this is an exam or interview-type of question, which are forbidden anyway.

With one command:

_MOVE_CORR structA structB

where _MOVE_CORR is defined as a macro containing the code from Kumar

Good point - that would be the answer to all of these "one command" questions.

Hi Sanjeev,

u can try like this.

Assume str1 has structure = wa1.

And structure2 has structure = wa2.

then try this ,

wa2-f1  =  wa1-f1.

wa2-f2  =  wa1-f2.

Please check it and confirm.
