# Basic description of functionality
Be.Smart ERP Picker is an add-in that runs within [Autodesk Inventor](/holixa-erp-picker/system-requirements.md#holixa-erp-picker-add-on-for-autodesk-inventor). The add-in can be run from within a part, assembly, or drawing environment. In the assembly, it is necessary to first select the component to which the information from the ERP system will be written.
The user uses the [Be.Smart ERP Picker](/holixa-erp-picker/erp-picker-inventor-add-on/overview-of-commands/be.smart-erp-picker.md) command to open the data source preview window, selects the row containing the required information (attribute values / values from columns), and double-clicks on the row to write these values into the iProperties of the Inventor document.
Which values from the selected row will be written to the iProperties of the document is determined when configuring the add-in using the \*.ini file (see [Section \[Mappings\]](/holixa-erp-picker/common-information/application-configuration/configuration-file-parameters/section-mappings.md) or[Section \[MappingsC\]](/holixa-erp-picker/common-information/application-configuration/configuration-file-parameters/section-mappingsc.md)).
