Definition:
This optional data item enables the individual CDS message to be classified as a normal or a test transaction.
Permitted values are:

CODE	CLASSIFICATION
T	The CDS Message contains Test CDS data
Other	The CDS Message contains production CDS data

Usage:
CDS data marked with a "T" in the CDS Test Indicator in the CDS Transaction Group Header will result in:
a) Delivery of the test marked CDS to the receiver as addressed;
b) The test-marked CDS will not be entered into the database;
c) Delivery of all other CDSs to the receiver as addressed;
d) All non-test marked CDSs will be entered into the database.
Production CDSs must not be marked as a TEST.
It is strongly recommended that Test and Production CDSs are not mixed in the same interchange.
A further test facility exists where the whole CDS Interchange is marked as TEST by setting the CDS INTERCHANGE TEST INDICATOR in the CDS Interchange Header.
Refer to the NHS CDS Manual for a detailed description of these processes.
