Hi

I do NOT agree  that it should be possible to delete data elements that
have datavalue or tracker records - in such cases where there is real DATA,
the user must assess and delete such DATA first or else leave the data
element no longer in use (with its data) - we typically move such
historical data elements to an "inactive" data set.

On the other hand, I have found many meta-data objects where deletion is
being blocked due to (sometimes random) records in other meta-data tables -
meta-data that clearly won't be relevant any more (e.g. various tables
called "....dimensionitems" is a typical example). It is also a huge
problem that when e.g. data elements - even data elements with no actual
data - at some stage were included in some favourite, deletion is blocked
AND the error message says nothing about WHERE it is used. I always end up
spending considerable time tracking those down in the back end and deleting
them, before being able to delete the data element itself. Audit trails is
another example of "process" data that no longer is useful when e.g. a data
element is deleted.

Regards
Calle
