To look up Protheus data dictionary fields and indexes, query the SX2, SX3, and SIX base tables. This validates metadata structure and confirms exact field definitions, index orders, and relationships to reduce uncertainty during ERP customization.

Mandatory SQL constraints for querying ADVPL dictionary metadata include applying soft-delete filtering, using lowercase column names, applying TRIM for character comparisons, and selecting base tables to prevent empty or incorrect query results.

To find triggers and standard lookups for Protheus tables like SA1, query the data dictionary for specific fields such as A1_COD and SXB/F3 configurations. This identifies validation triggers and standard lookup behavior attached to the table.

Yes, you can validate the impact of code refactoring on Protheus MV parameters and triggers by querying the data dictionary. This confirms whether planned code improvements affect existing parameters, triggers, or table relationships before migration.

Protheus dictionary queries return empty results for SX3 field metadata when mandatory constraints are ignored. Failing to use lowercase columns, apply TRIM for character comparisons, or filter soft-deleted records prevents accurate base table data retrieval.
