You can use parameterized commands in object forms to pass some parameter (for example, a value of a reference attribute) to a command handler. This parameter will be available for further use, for example, you can open a report form using the parameter.
We will explain this on the example of a command that opens a Balance of materials report for a warehouse specified in a document. The report is opened from the Services document form, and the Warehouse document attribute value is passed to the report. When the report is opened, a filter by the Warehouse parameter is added to the report settings.
