Validate Data

Data validation allows checking the correctness of model records according to established rules and constraints. This instruction will show how to perform data validation in a model.

When Needed

  • You need to check the correctness of data in a model.
  • You want to find records with errors or incorrect values.
  • You need to make sure data complies with established validation rules.
  • You want to import data and check it before saving.

What's Important to Know

  • Data validation — checking records for compliance with rules and constraints.
  • Validation can check field format, required fields, value ranges, etc.
  • Validation results show which records have errors and what problems were identified.
  • You can fix errors directly after validation.

Prerequisites

  • You are logged in with analyst rights.
  • You have navigated to the Custom Data module via Apps -> Custom Data.
  • You have an opened model with records for validation.

Step-by-Step Instructions

  1. In the Custom Data module, open the needed model.
  2. Find the "Validate Data" or "Check Data" button (usually located above the records table or in the actions menu).
  3. Click the button — the system begins checking all model records or only those you previously selected.
  4. Wait for validation to complete — the system displays results:
    • Number of checked records.
    • Number of records with errors.
    • List of errors for each problematic record.
  5. Review validation results:
    • Find records with errors in the list.
    • Review the description of each error.
    • Fix errors directly in records or through bulk editing.

What Happens After

Validation is completed, and you see all errors in the data. You can fix errors to ensure model data quality.

How to Verify It Worked

  • Check that validation is performed and results are displayed.
  • Make sure all errors are identified and described.
  • After fixing errors, repeat validation to ensure all problems are resolved.

Other Methods

  • Some systems perform validation automatically when saving records.
  • You can configure automatic validation for certain fields or records.
  • Use validation before importing data to check files before uploading.
