auto (re-)lookup?

[stefangs]

if i have a field that looks up the contents of a calc field in another file, can i somehow have it update automatically when the calc result changes?

i know i can use relookup, but that requires an action, and a live calculation is no good, because i want to use the field for relationships and then i can't be indexed.

Why not just make it a calculation where it equals the other field.

stephan, I think you have found the catch-22 of updating match fields. You can't use a calculation that includes related fields because it cannot then be indexed, which means it can't be used in a relationship.

I deal with this issue in three ways, all use a non-calculated match field with scripts to set the value (or relookup)

1. Use scripted data entry processes that can also update the match field.

2. Have scripted update scripts that update only the relevant record set at the time the relationship will be needed (this only works for some situations.)

3. Use daily update scripts to go through and update the match field for all records in the database.

Oops, I missed the part about the relationship.

Sorry

thanks - i almost thought that you couldn't do it as easily. i'll just go for a scripted thingy then... thanks again!

I think that you may be able to enfold your function in the Evaluate function, with the triggers being your lookup fields.
