Problem using HASH TABLES

[Former Member]

Im trying to use hash table in a program but Im gettin an error I cant understand...

DATA gt_kna1 TYPE HASHED TABLE OF kna1 WITH UNIQUE KEY kunnr.

SELECT kunnr INTO TABLE gt_kna1

FROM kna1.

Im gettin this error:

An entry was to be entered into the table "\PROGRAM=ZTABLA_HASH\DATA=GT_KNA1" (which should havehad a unique table key (UNIQUE KEY)).

However, there already existed a line with an identical key.

But this is impossible, the field kunnr is key in table kna1.

Does Anybody know why Im gettin this dump?

Hi,

Use this code now it will not go dump.

DATA gt_kna1 TYPE HASHED TABLE OF kna1 WITH UNIQUE KEY kunnr.
SELECT kunnr INTO corresponding fields of TABLE gt_kna1
FROM kna1.

Regards and Best wishes.

Try this way

TYPES: BEGIN OF TY_KUNNR,
         KUNNR  LIKE KNA1-KUNNR.
TYPES: END   OF TY_KUNNR.
DATA:  IT_KUNNR  TYPE  HASHED TABLE OF TY_KUNNR  WITH UNIQUE KEY KUNNR.
SELECT KUNNR INTO TABLE IT_KUNNR
FROM KNA1
