H2 requires various DHIS2 options, data elements, attributes and other objects so a HNQIS checklist can be run on a given DHIS2 instance.
The required metadata is either included on a H2 export created on another server or installed by the PCA - the dedicated DHIS2 web app that allows you to configure HNQIS checklist.
