I am not sure if I understood your question correctly, but I can say that the system provides an unlimited number in the sense that I have never encountered any restrictions in terms of creating COs. I can create as many as I want. Could you please elaborate on your question? What prompted you to ask such a question?
Firstly, let’s set aside DHIS2 for a moment. It seems impractical to assign 1000 category options under a single category. The fundamental purpose of a category is to group category options together that are intended to be used simultaneously by one or more data elements or indicators. Thus, the question arises: Is it feasible to have an indicator or data element that utilizes 1000 category options? My answer is no—this is impractical. Even finding a data element that uses 100 category options would be exceedingly rare.
Therefore, my advice to you is not to combine category options that do not function cohesively.
I acknowledge that my view might be biased. Could you please provide more reasoning behind your preference for a single category to encompass 1000 category options?
In Data visualizer all the options will be available for all health facilities within the district so how did you manage to remove the duplication of options and keeps only options which had a relation with their health facilities.
District Dog has 2 facilities 1 and 2
Facility 1 has A and B options
Faciliry 2 has X and Y options
In data visualizer after adding category die data is shown as:
Facility 1 A
Facility 1 B
Facility 1 X
Facility 1 Y
Facility 2 A
Facility 2 B
Facility 2 X
Facility 2 Y
