Update sql instruction problem

[Former Member]

Hi,

I have a big problem with Update instruction.

When I execute the first update is all right (sy-subrc eq 0 ), but when I execute the second update on the same table (pa2007)

not work and sy-subrc is 4.

Between first and second update I change only value of subty field.

 LOOP AT tb_pa2007 INTO wa_pa2007.

    IF wa_pa2007-subty EQ '03' OR wa_pa2007-subty EQ '04' OR wa_pa2007-subty EQ '05'.
      MOVE '02' TO wa_anwko.
      MOVE '02' to wa_subty.

      UPDATE pa2007
      SET ktart = wa_anwko
             subty = '02'
      WHERE pernr = wa_pa2007-pernr
        AND begda = wa_pa2007-begda
        AND endda = wa_pa2007-endda
        AND subty = wa_pa2007-subty
        AND sprps NE 'X'.

     ENDIF.

 ENDLOOP.

Maybe duplicate key ? Since you are updating 3 different subtypes into one, when you try the second update it might be trying to update to an already existing key record.

Anyway, and this is just a suggestion, updating PA tables in this fashion is not the most recommended, there is a FM for this which ensures that the validations are done as if you were doing these changes in PA30. FM is HR_INFOTYPE_OPERATION.

Thank you very much!!

The problem is the SEQNR number.
