move corresponding question

[Former Member]

I would like to do the following in abap:

move-corresponding ls_a TO ls_b where ls_b-components are initial.

Do anybody know a good way to do that?

[Former Member]

hi,

hope both ls_a and ls_b are structure.

syntax will be

If ls_b-(component1) is initial

and ls_b-(component2) is initial

and ls_b-(component3) is initial

.............

move corresponding ls_a to ls_b.

endif.

for further detail check

if both are having the same structure ..

U can write.

ls_b[] = ls_a[] .

[Former Member]

if ls-b is initial.

move-corresponding ls_a TO ls_b .

endif.

these two structure must have the same structure

Hi,

U can move field by field........from lc_a to lc_b...

Hi,

Check each individual component for value.If it is initial then move components to ls_a TO ls_b.

IF ls_b-component1 is initial.

MOVE ls_a-component1 to ls_b-component1.

ENDIF.

Hi Eza ,

You can use Move Corresponding for tranferring the data from fields from structure Ls_a to same fields in structure Ls_b .

It will work perfectly fine and data tranfer will take place for common fields from Ls_a structure to Ls_b .

Hi,

Move-corresponding will move all the fields from one internal table to another having similar fields.

So to transfer all entries into another internal table we can have move-corresponding itab1 to itab2.

or u can use itab1[ ] = itab2[ ].

If they have same structure.

If we take into account the performance the itab1[ ] = itab2[ ] is much faster than move-corresponding, as move-corresponding has the bottle neck to search all fields of similar name.

Ur code could be :

IF NOT ls_b[] IS INITIAL.
ls_a[] = ls_b[]
ENDIF.

Hope this helps you.

thanx.

Use Like that

Loop at ls_a where components are initial.

move-corresponding ls_a TO ls_b .

Endloop.

Thanks.

Not excactly what I was looking for, but thanks..

Wnat to have something that checks for every field if it is initial.

not for the hole structure.

mapping of those fields which are initial in the goal structure.

[Former Member]

do like this ..

loop at ls_b .

case : field1 .

when space .

ls_a = ls_b.

endcase .

endloop.

[Former Member]

when U try to move for the first time every field would be initial.

Instead loop at ls_a .. and read ls_b with the key field ..

Loop at ls_a.

read table ls_b with key feild1 = ls_a-field1.

if sy-subrc = 0.

if ls_b-field2 is initial.

ls_b-field2 = ls_a-field2.

endif.

Similarly write for others ....

endif.

endloop.

If you know the structures, then you should code it separately for each component of the structures.

i.e.

IF ls_b-comp1 IS INITIAL.
  ls_b-comp1 = ls_a_comp1.
ENDIF.
IF ls_b-comp2 IS INITIAL.
  ls_b-comp2 = ls_a_comp2.
ENDIF.
etc.

If you don't know the structures, and assuming they have the same structure, then use field-symbols. This isn't as fast as when you do, but still not too bad.

DATA: l_count TYPE i.
FIELD-SYMBOLS: <src> TYPE ANY,
              <dst> TYPE ANY.

DO.
  ADD 1 TO l_count.
  ASSIGN COMPONENT l_count OF STRUCTURE ls_a TO <src>.
  IF sy-subrc IS NOT INITIAL.
    EXIT.
  ENDIF.
  ASSIGN COMPONENT l_count OF STRUCTURE ls_b TO <dst>.
  IF sy-subrc IS NOT INITIAL.
    EXIT.
  ENDIF.
  IF <dst> IS INITIAL.
    <dst> = <src>.
  ENDIF.
ENDDO.
