Im trying to edit the connector in the cable end in the attribute but it is not happening and its not showing in the cost summary

Reports such as Cost Summary, Cost Detail, Price Summary and Price Detail list products that are represented by Symbols.

Cables and their attributes are listed in Cable Schedule reports (which exclusively report on Cable and Dogleg objects).

Note that to show Connectors you will need to modify one of the Cable Schedule reports to include fields for those attributes, using the names Detail_CS_Start_Connector and Detail_CS_End_Connector.  For more on customizing reports see http://www.stardraw.com/products/stardrawav/FAQ.asp?FAQ=RA001

I hope this is helpful.

Kind regards,
