Recently, I came across one issue while working with one Customer where they were facing bit of challenges to update existing working Integration with new JSON field input.
So, in this use case, two integration orchestration process flow are involved, Master Integration and Child Integration both working well in production. However, time to time developer gets requirement from business to enrich this working flow by adding more fields into Child Integration which was interacting with Oracle Responsys System. The Master Integration getting data from NetSuite, passing Child Integration same data which was interacting with Responsys and completing business flow.
Here is flow diagram with existing working flow Vs flow with new requirements and highlighted problem area.
Once developer add new fields into Child OIC orchestration flow, saved, activated and tries to refresh the Parent OIC orchestration flow, it breaks existing mapping. Behind the scene obviously since Child Integration orchestration flow input payload got changed it has cascading impact on calling Integration flow and calling Integration flow fails to deduct those changes and breaks existing mapping and wiped out existing mapping. see the relevant snaps –
