SELECT * FROM /BIC/ASALHDR0100 into Table CHDATE.


SORT CHDATE by DOC_NUMBER.
SORT SOURCE_PACKAGE by DOC_NUMBER.


LOOP AT CHDATE INTO WA_CHDATE.
   READ TABLE SOURCE_PACKAGE INTO WA_CIDATE WITH KEY DOC_NUMBER =
   WA_CHDATE-DOC_NUMBER BINARY SEARCH.

   MOVE WA_CHDATE-CREATEDON  to WA_CIDATE-CREATEDON.
 APPEND WA_CIDATE to CIDATE.

ENDLOOP.

Hello,

try a select like the following one instead of you code.

SELECT field field2 ...
INTO TABLE it_table
FROM table1 AS T1 INNER JOIN table2 AS T2
ON t1-doc_number = t2-doc_number

You can go for parallel cursor method.
