Read statement is used to retreive only one record from internal table.
Note: While using read one should have all primary keys..otherwise subrc will fail.

Read statement is used to read a single record with the loop...endloop.
Its an effective statement which reduce the unnecessary nested loops and helps in improving the performance of the program.
For EX: if you read the invoice header with the the invoice item records then you are avoiding one more loop with the line items ....

READ: Using read statement we can read data from one internal table to another internal table.

exp : IN program having 3 internal table.

         one for Header data.
         one for item data,
         one for final internal table.

using READ statement we can move first and second internal table into final internal table based on the key fields.
