Further Options to Control Selection

TOP

Method SET_TOP( ) enables the number of hits to be restricted.

Example:

Code Syntax

gp_log_api->selection( )->set_top( 5 ).

This means that only the first five logs found are returned as the result of the selection.

Skip

Method SET_SKIP( ) enables the selection results to be skipped.

Example:

Code Syntax

gp_log_api->selection( )->set_skip( 10 ).

The first ten logs found are skipped, and the first result returned is the eleventh hit in the database.

Order by

By default, the selection results are sorted by log number. If a different sorting is required, the relevant criteria can be passed to method SET_ORDERBY(.).

Example:

Sample Code

gp_log_api->selection( )->set_orderby(
  VALUE #( ( fieldname = 'STARTUSER' descending = abap_true )
           ( fieldname = 'LOGID'     descending = abap_false ) ) ).

The identified logs are first sorted in descending order by user name and then sorted in ascending order by log number.
