Definition

Use

If you set this indicator, the system tries to reduce the number of calls of the secondary search connector in query join scenarios. The number of calls needed depends on the following factors:

  • the selection modes of the input fields of the secondary search connectors that are used in the join criteria
  • the number of different values the primary search connector returns for these fields during the execution of a query

The systems calls the secondary search connector exactly one time if the following applies:

  • the selection modes of the input fields are either Multiple Values or Select Option
  • it is guaranteed that the primary search connector always returns exactly one value for each input field of the secondary search connector

In all other cases, the system has to call the secondary search connector multiple times to retrieve all necessary result data. This may result in extended runtimes.

The system tries to reduce the number of calls by not passing on values for input fields for which you did not set the Required indicator. Instead, it uses these values to filter the result data returned by the secondary search connector. Since the system reads more data than needed, this functionality may result in extended runtimes or, in extreme cases, even in aborting query processing due to lack of memory.

Dependencies

If the reduced number of calls is still higher than the value you entered in the Maximum Executions field, the system aborts query processing with an error message.
