Adjust the Master Index Configuration

Based on the results of the final frequency analyses (see Performing Frequency Analyses on Cleansed Data), you might need to adjust the configuration of the master index application by adjusting the block fields if the frequencies are too high and by setting the relative match weights based on how unique each match field is. The results could also indicate that you might need to define exclusion files for the Initial Bulk Match and Load tool or filters for the SBR filter so certain values are not used for matching. For example, if there are a large number of SSN fields with the default value “000–00–0000”, you can exclude that values from the blocking process, the match process, or the survivor calculation for the single best record.
