Effect
Loop processing of the database table dbtab .You must declare the table dbtab under TABLES in the program. dbtab is a table name which begins with "T" and consists of up to five characters.The processing is the same as for variant 1 (except that the system field SY-TABIX is not set). If you want to process the whole table, you must set all table fields to SPACE . Otherwise, the table fields you want to use as a generic argument must be filled beforehand.
Fields of type P and type N have an initial value other than SPACE . This means that fields of this type after CLEAR or MOVE SPACE TO ... are not set to SPACE .
In the case of tables which have arguments containing fields of type P or type N , the entire table header line must be set to SPACE ( MOVE SPACE TO dbtab , not (!) CLEAR dbtab ). It is preferable to use SELECT instead.
