In my previous article I mentioned how to create an external list using SharePoint 2013 to read list and read a particular list item. in this article I am planning to show how to allow adding new list items and editing list items which were disabled earlier.
I will be referring to the Visual Studio solution I created in previous article which can be found here. The step by step guide is as follows.
1. Double click on VSDemoModel to open the VSDemoModel.bdcm in the designer. The Entity1 object will be available. Select it. In the 'BDC Method Details' window you will find the 'ReadList' and 'ReadItem' methods. Scroll down the window till you find a cubic icon followed by a text '<Add a Method>'.
Upon clicking on it, a drop down list will appear. Select 'Create creator method' option. A new method will be available as 'Create'.
