Ellie,

You should be able to do this using the batch update tools. Try this:

Tools > Run Batch Updates > JNCC > Determination Updated > Det6 - Creates new Determination using original taxa

I think that should do what you want. If not, give Mike Weideli a shout - he usually has this sort of batch update knocking about already and so it's well worth asking him.

Regarding Correct vs. Considered Correct. Correct is when you know something is definitely correct (you have a specimen that has been looked at by a couple of experts, or you have a photograph that conclusively tells you the id is correct), whereas Considered Correct is when you assume it must be correct because the id has been made by an expert or it's an easy id, but other than that, you don't necessarily have any proof.

Thanks Charles,

I have had a look at the batch updates, but I don't think Det6 is quite the one that I need.  It says that it is for selected surveys 'where the system custodian is not the custodian of the current determination. Use on imported Surveys...'

I need to update records that we have entered ourselves, not records that we have imported from someone else.  I will contact Mike Weideli & see if he has something useful.

Thanks for the clarifications on Correct & Considered Correct, they're very useful.

Cheers,
Ellie
