Hi Musa,

"The Insert statement conflicted with the foreign key constraint..." this error comes when you are trying to insert a NULL VALUE in a referenced attribute of an entity. Before you use Create or Update entity action, make an assignment to the referenced attribute by assigning a proper ID to that attribute, then you will not get this error.
