Hi,

can any one help me how to write dyanamic READ statement

If we do not know the name of a component until runtime, then how we can use the expression WITH TABLE KEY ... to specify it keys dynamically .

please send some sample code to illustrate

thanks...

Hai Bobby,

Do you want to pass the fields dynamically ? Then use the statement

read table it_tab with key (fieldname) = 'VALUE'.

hi,

try:

DATA key1(72) VALUE 'BUKRS'.

...

read table itab with key (key1) = ztab-bukrs.

DATA: T LIKE STANDARD TABLE OF BKPF WITH HEADER LINE.

DATA: FIELD1(10),

FIELD2(10).

FIELD1 = .....

FIELD2 = .....

READ TABLE T WITH TABLE KEY (FIELD1) = <VALUE>

(FIELD2) = <VALUE>.

DATA: T LIKE STANDARD TABLE OF BKPF WITH HEADER LINE WITH NON-UNIQUE KEY BUKRS BELNR.

DATA: FIELD1(10),

FIELD2(10).

FIELD1 = .....

FIELD2 = .....

READ TABLE T WITH TABLE KEY (FIELD1) = <VALUE>

(FIELD2) = <VALUE>.

Hi,

1.You can fill the fieldname statically or dynamically using cl_abap_*type classes.

2. you can fill the fieldvalue using ASSIGN ...COMPONENT

variant like this..

field-symbols: <lv_field_value> type any.

ASSIGN COMPONENT fieldname

OF STRUCTURE ls_strucure_name TO <lv_field_value>.

If it is assigned sy-subrc will be 0.

Regards,

Suresh
