When you deactivate the dataset in Cloud, the PSO dataset gets expired. Re-activating it doesn’t help as it is still expired, you need to send a full load.
I did try several times to send full load from the IFS cloud, but no way. I found some WAITING Optimization Framework application messages with the following error:
ExecutionException from Sender thread Caused by: ifs.fnd.connect.senders.ConnectSender$TemporaryFailureException: Exception while sending data Caused by: ifs.fnd.connect.http.InternalServerErrorException: InternalServerErrorException: 500#{"Code":3,"Type":null,"Message":"FAILED"}
I cancelled them and sent new Full Load, also didnt help. I managed to create a new dataset as iam in test env.
