Integration control used in making conditions for processing provides a way to match xml field or object field with particular value. We have 4 types of integration control 1. Value 2.List 3. XRef 4.Boolean Value control is used to compare with single value. List control is used to compare with list of values which may come from domains. Boolean control is true or false value used to compare yorn field I personally never used it. XRef control i.e cross reference control is used to to swap values foe example we have different orgid in other system than we can define cross reference control inorder to translate. We create cross reference control and associate it with enterprise service or publish channel. We can also override these values at external system level.
