Creating and Maintaining Category Combos @ PSI - User Role/Authority
The assignment of the authority to crate create and maintain category combinations (private or public) is severely restricted at PSI due to the consequences that an inappropriate cat combo number of combinations can have in the overall health of the system. Users are given access to this authority after individual assessment of their DHIS2 knowledge and database/ system management experience. PSI’s DHIS2 server suffered of various cases of millions of cat combos being created, which made the server unusable for a couple of days, and required a significant clean up process.
