SCLM uses a data set when it expects that the data set already contains a member (for example, when attempting to delete a member), or when the data set will contain a member (for example, when saving a new member). The following list details how SCLM functions use a data set:

Build

Uses a data set if it contains a member that has a corresponding accounting record and that member is being built or referenced by another member that is being built. Build also uses data sets for output (those referenced by the LOAD, OBJ, or LIST architecture keywords, for example).

Promote

Uses a data set if it contains a member that has a corresponding accounting record and that member is being promoted. If these data sets contain members that need to be promoted, they must be present in the current group and in the group being promoted to; otherwise, an error message is issued. If a promotion occurs from a non-key group to a key group, the corresponding data sets at the previous key group will also be used.

Delete

Uses a data set when deleting a member.

Delete from Group

Uses a data set when deleting a member.

Library Utility

Uses a data set when deleting a member or when Edit, View or Build are invoked.

Import

Uses a data set when VSAM records are being imported into the hierarchy. The member imported must exist somewhere in the hierarchy view for the group being imported into.

Edit

Uses a data set when storing or retrieving a member.

View

Uses a data set when retrieving a member.

Migrate

Uses a data set to retrieve information about a member that is being migrated into the SCLM hierarchy.

Parse

Uses a data set when parsing a member.

Package Backout

The package details file contains an entry for each package, listing the members in that package. This is built by Promote and used by Package Backout.
