It seems like there are not DeleteItem and UpdateItem for Items. This seems like it would be a common function. Any ideas on how this can be achieved? Just a note, I am not using the e-Connect, I am using the web services.
Ye there are not WebMethod to Delete and Update Item; I will suggest you to create Custom WebService using eConenct to Update Item and use Web Service WebMethod to "Discontinue Item" and In Year End process you can remove all Dicountinue items.
