With a network selection, CA IDMS Extractor automatically selects all records and sets accessible in the entire structure. When you make a network selection of a record in index, CA IDMS Extractor marks it as an Entry Record or Entry Index. All owners of sets of which the Entry Record or Entry Indexed record is a member and, which do not already participate in a path and which are not indexed by an Entry Index, are selected in the path. All selected records that are themselves owners or members of sets are treated as if it were an Entry Record.
There is an exception to the network selection process regarding a Bill-Of-Material (BOM) structure. The AUTOMATIC member of the BOM set is selected walking from the BOM record to the junction record. The MANUAL member of the BOM set is selected walking from the junction record to the BOM record.
The Record Level Selection Criteria for all records selected in this manner indicate to extract all record occurrences. You may modify the selection criteria of any or all of these records to limit the number of records extracted.
You should verify that sets are walked in the manner in which you want them walked, that is, from owner to member or member to owner. CA IDMS Extractor may select a set as being walked from member to owner when you really want the set walked from owner to member. If this is the case, you must deselect the set and then select it again using a manual selection.
For a data structure containing recursive records (records that are accessed by more than one set type in the same path), CA IDMS Extractor sets the number of levels to extract to zero. You may need to modify this value. Refer to Recursive Data Structures for more information.
