You can achieve your objective by ‘integrating’ your tracker data with aggregate data elements which already have the category combos you desire. You will need to create and ‘map’ multiple program indicators to the aggregate data elements. Then you will synchronise the tracker data to aggregate.
There are various tools which can help you achieve this
- PDAC tool: will help you generate all program indicators needed for disaggregations using a ‘base’ program indicator. This is especially useful if your implementation deals with a high number of disaggregations (category option combinations) and/or attribution (attribute option combinations). The PDAC tool is an app that can be installed from the DHIS 2 App hub
- Aggregate data exchange service will help synchronise tracker data to aggregate by creating an aggregate data exchange and defining parameters to use. However, there are limitations to using this service. Custom scripts can be used to overcome the limitations
