The Duplicate context menu command copies the selected data set and allows you to change the ERP fields, but not the geometry data.
Select the desired data record and select the desired options in the Duplicate rows [Duplicate line] dialog.
If this option is selected, the Generate value sequence dialog appears (see above under Set fields)
Create duplicates without value [Create duplicates without assigning values] assignment (copies the fields of the link table)
Create duplicates with values from the [Create duplicates with values from the source line] source line (Values of the erptable are only copied if an ERP number has been assigned)
With this option you determine explicitly desired values. Enter them in the input fields.
