Q:

lotusnotes: creating a new field, update the already existing documents

I create a new computed field called txt_new in a form, which has a default value based on some calculations between other fields. 
I also create a new column in my view named vwMain which has the default value: txt_new.
The problem is that the column is empty considering the fact that the .nsf has already >10k documents. Is there any posibility to update/(re)save the documents in a safe method ? 
Thanks for your time!

A:

Write an agent which contains the default formula of your field txt_new and execute agent for all 10K documents. That should be fast enough or to be more exactly: there is no faster way.
Example for agent:
SELECT txt_new = "";
FIELD txt_new := ... here is your default formula code ...
