Hi,
In your SP itself you can insert data into 3 tables...
please follow the below syntax.
CREATE PROCEDURE XXXX
(
@Trans_Type VARCHAR(100),
)
AS
BEGIN
IF @Trans_Type='INSERT-A'
ELSE IF @Trans_Type='INSERT-B'
ELSE IF @Trans_Type='INSERT-C'
END
you can do like this also....
I think it might be help for you....
