Hi,
comparing with read statement is used specific fields of internal table are compared.
if u Transporting with read statment only those fields specified with transporting are copied into the work area.
example is:
DATA: BEGIN OF LINE,
COL1 TYPE I,
COL2 TYPE I,
END OF LINE.
DATA ITAB LIKE SORTED TABLE OF LINE WITH UNIQUE KEY COL1.
DO 4 TIMES.
LINE-COL1 = SY-INDEX.
LINE-COL2 = SY-INDEX ** 2.
INSERT LINE INTO TABLE ITAB.
ENDDO.
CLEAR LINE.
READ TABLE ITAB WITH TABLE KEY COL1 = 3
INTO LINE TRANSPORTING COL2.
WRITE: 'SY-SUBRC =', SY-SUBRC,
/ 'SY-TABIX =', SY-TABIX.
SKIP.
WRITE: / LINE-COL1, LINE-COL2.
The output is:
SY-SUBRC = 0
SY-TABIX = 3
0 9
The program fills a sorted table with a list of square numbers. The READ statement reads the line of the table in which the key field COL1 has the same value as in the work area and copies it into the work area. Only the contents of COL2 are copied into the work area LINE. SY-SUBRC is zero, and SY-TABIX is 3, because ITAB is an index table.
