Description
You can use the change log to gain an overview of changes in most windows of SAP Business One. Each time you update, for example, tax groups, withholding tax, house banks, freight, credit card, authorizations, sales, purchasing documents, production orders, charts of accounts, or UDOs, you can use the ChangeLogsService service to look up the change logs and show the differences between two change logs.
