Supporting documents
- Prepare internal classification of products and services.
Completing and checking data
- Open “Item groups” for the active company and search for the existing record before adding a new entry.
- Compare code, name and items in the group with the documents. For an existing item, select the row and choose “Edit row details” in its details and options window, then correct only information you can justify in the form. Calculated values and historical links remain available for checking only.
- Use the same classification when comparing periods. Commercial grouping alone does not determine deductibility or VAT treatment.
- Check the form and save the item. Close the form before adding or editing another item.
- Continue to the page using these details and check the record in the transaction's context, including its effect on reports.

Compare identification and details determining the record’s purpose: code, partner, unit, stock location or period as applicable. Check documents using each record. Choose the record reflecting reality; do not rename or remove a used record merely to hide a duplicate.
