Read a local Table after modifying it

Former Member — Thu, 24 Jul 2008 13:20:36 GMT

Hi Gurus.

I have a local table lt_table.

At some point of my code I modify that table using indexes and it works well.

The problem is that after I change that table I cannot read it into a structure with the changes being reflected.

Something like this.


DATA: 
          i type sy-tabix,
          lt_table type table of bla,
          ls_table type bla.


LOOP AT SOME_TABLE INTO SOME_WA.

   READ lt_table into ls_table
   WITH KEY field1 = SOME_WA-field1
   BINARY SEARCH.

   ...

   MODIFY lt_table FROM ls_table index i.

ENDLOOP.

After I modify the table, I can see in debug that the table was modified but the structure ls_table doesn't see the new results...

Is this normal behaviour from ABAP?

Thank you for your replies.

Jorge

LOOP AT SOME_TABLE INTO SOME_WA.
  
   READ lt_table into ls_table
   WITH KEY field1 = SOME_WA-field1
   BINARY SEARCH.
  if sy-subrc eq 0.
 i = sy-tabix.
 .....
  ... 
   MODIFY lt_table FROM ls_table index i.
   clear ls_table.
 endif.
ENDLOOP.

if you don't use clear. and then check ls_table you will see old data only.

where are you reading. which index you are reading that also matters.

Hi,

check by using,

MODIFY <itab> INDEX <idx> FROM <wa> 
       TRANSPORTING <field>.

Your looping criteria is on SOME_TABLE and modifying ls_table where only the work area will be modified.. so keep looping in a reverse way to incorporate your modified changes
