Voice of Customer (VoC) is a excellent tool for survey editor right in CRM, though it still lacks some nice to have functionalities. I’m not going to discuss about VoC in this post.
Survey Response is a entity collecting all Answers for Questions in the Survey. When user submits the survey, Survey Response and Answers will be created in CRM from Azure. The Survey Reponse will be created first and then related Answers will be created and look up to the Survey Response. This happens asynchronously.
So if we want to trigger a plugin or a workflow on Survey Reponse, we want to make sure the Survey Reponse has been created and all related Answers have come through. We shouldn’t trigger it on creation of the Survey Response as not all the Answers created in CRM; we shouldn’t trigger on creation of Answers either as Answers are created unorderly, the last answer may be created first. Instead, we should use an OOTB field called “msdyn_processingcompletetrigger”, it will be updated to Yes if the Survey Reponse and all Answers are created.
Cheers!
