Content

Hi,

I am using soap api and .Net framework to find and create trading partner items in scm application. I successfully used findTradingPartnerItem to get trading item partner with filter but i can't find what is the correct payload for createTradingPartnerItem.

I tried:

 TradingPartnerItemService tpiService = new TradingPartnerItemService();            TradingPartnerItem newTpi = new TradingPartnerItem();

newTpi.TradingPartnerItemNumber = "Tpi number example";
newTpi.TradingPartnerName = "exist trading partner name example";

newTpi.TradingPartnerItemDescription = "";
newTpi.TradingPartnerType = "MANUFACTRER";(the type of the exist trading partner)
newTpi.TradingPartnerNumber = "4061"; (the number of the exist trading partner)
newTpi.TradingPartnerId = 100000001679311;(the id of the exist trading partner)
