Client Specified Select

Client specified clause switches off the automatic client handling by open SQL. If we select the MANDT (client) field then we have to use client specified clause like follows:

  SELECT mandt field1 field2 ... fieldn
    INTO TABLE internal_table FROM database_table
    CLIENT SPECIFIED  "MANDT has been selected
                      "hence client specified is must
    WHERE mandt = '800'
      AND field1 IN select_option.

This statement is always mentioned after the FROM clause. If the addition CLIENT SPECIFIED is specified, but the client ID in the WHERE condition is not mentioned, the SELECT statement circumvents the SAP buffering.
