# What if I Have the Same Custom Data Field in Two Lookup Tables? Which One Is Reported?

> When a matching field exists in multiple Lookup Tables, Invoca reports the last match, processed in alphabetical order by table name.

If a call matches fields in more than one Lookup Table, Invoca processes all your Lookup Tables and reports the last match, sorted alphabetically by table name (not file name).

To control the order tables are processed in, use alphabetical prefixes on your table names — for example, "01\_Table Name," "02\_Table Name," and so on.

**Applies to:** Lookup Table, Marketing Data, call reports
