Lars,

We had a nearly identical issue with one of our database on Friday -
importing one new orgunit from another databaseinstance resulted in
duplicates in the orgunitlevel table, which in turn caused analytics to
fail.

The key design issue (I would not call it a bug, even if it appears like
that) here is the data and meta-data import functionality in DHIS2 does not
assist users to avoid such duplication by
- identify potential duplicates by checking e.g. name or level or UID
- display the potential duplicates to the user to enable her/him to modify
or drop the conflicting records.
This type of import checks have been in DHIS 1.4 for a long time.

This design issue does not only affect the orgunitlevel table - it affects
much more profoundly the whole categoryoptioncombo and attributeoptioncombo
system, where it is very easy to end up with multiple versions of in
reality the same categoryoptioncombo name (but each with it's own internal
id and uid). That in turn causes havoc with e.g. indicators, because the
indicator engine seemingly randomly picks the first of those duplicates it
find. This issue has required many days of cleaning up in the back end for
at least two country systems I've worked on recently (Namibia and Lesotho).

Any chance we could have a round-table discussion on how to re-design the
import processes to handle this better?

Regards
Calle
