In case Suppose you have a decentralized Advance Advanced Adapter Engine. In that case, you need to define a separate environment for each engine in the IFTT IMG. General customizing for each of them needs to be performed via configuration wizardInitial Customizing.
For each of the AAE, you need to configure a separate “Dummy” ICO per the installation manual. Sender channels needs need to point to the correct AAE. Assign those channels correctly in IFTT Environment Parameters.
While fetching or executing test cases, please choose Environment corresponding to AAE, where the messages for the given test case are stored.
