Use this field in the Suggested Order Report (RSO) to define how vendors are assigned for the report. L = Line/Subline; P = Part. Part assignment requires vendor assignment on each inventory record. The norm for automotive businesses is Line/Subline and is based on the vendor record line mapping from the Lines tab in Vendor Maintenance. Line/Subline also uses the value in the field named “Select Lines/Sublines where vendor is” to define the lines and sublines to be included in the report.
