QAD ICT is a service product and should be installed as any other customization you receive from QAD Services. In this installation guide, it is installed in the $QADICT layer.
QAD recommends that QAD ICT should be first installed in the test environment and (if approved) then in the production environment.
Note: QAD ICT uses message numbers from 39100 to 39199. It is highly recommended that you delete all custom messages in the 39100-39199 range because they will be overwritten during the ICT installation process.
