</div>It is possible to delete categories. But if they are used it will be prevented.<br>
<br>
Exprire should remove them from drop down menu after some time (caching). If this is not the case, it is a bug.<br>
<div class="im"><br>

<br>
</div>Sometimes it is the only way. It is acceptable as a developer.<br>
<div class="im"><br>
> I did an import of my data to another instance.<br>
The import worked quite well but I will now see the newly imported categories AND the old values which is not what I want.<br>
<br>
</div>This i normal.<br>
<div class="im"><br>
> I am fully aware of the problems which might be related to deleted customising, but I have made some tests and found that even if a category value does not exist anymore ERP5 handles it quite well and does not dump.<br>
<br>
</div>The solution is normally to use expire. Then update all existing data so that none of it used "legacy" categories. Then expire them. Then after some time, deleted expired categories.<br>
<br>
Make sure also you do not break categories related to security configuration.<br>
<br>
