CALCULATE ASSO

AC space is based on the device type and the estimated number of records in the related Data Storage file.

NI/UI calculates index values for a single descriptor, requiring you to estimate such things as the average descriptor length, the number of multiple descriptors you expect to have, the total number of unique descriptor values for that field, an Associator padding factor, and a device type if other than the default.
