syst_instance_type_applications


Description

A many-to-many relation indicating which Instance Types are usable for each Application.

General Usage

Note that creating ms_syst_data.syst_application_contexts records prior to inserting an Instance Type/Application association into this table is recommended as default Instance Type Context records can be created automatically on INSERT into this table so long as the supporting data is available. After insert here, manipulations of what Contexts Applications require must be handled manually.
