Forum Post: Looking for GP web services API for creating Item Serial Number Master

Hi, I am using SOAP/WSDL in php to access Microsoft Dynamics GP 2015 web services. Please note that this is not SBA based GP Service. I am using old Dynamics GP web services) I know that there is an api (CreateSalesItem) for creating item to add item to ItemMaster. But I could not find an api (something like CreateItemSerialNumber) for adding/creating a record of Item Serial Number Master to add it to ItemSerialNumberMaster. Any ideas about api CreateItemSerialNumber ? Thanks for any help!
