Setting Field Locks

If a *DSNR accesses the Edit Field Details panel,CA 2E sets an *EXCL lock on both the field and its referencing file, if any. If the field is referenced by other fields, all reference (REF) fields in the domain are also locked, including the REF field’s referencing files. These prevent other developer’s from accessing an incorrect field definition while the field is being updated.

If a *PGMR accesses the Edit Field Details panel,CA 2E sets a *READ lock on the field, but does not lock files. This prevents *DSNRs from updating the field while it is used by a *PGMR.
