Do you have the list of users and target data for those users? It is most likely because of the same reason I mentioned above, if you analyze the data for users for which it is failing we can find it.
Hi @iamksatish I just saw that this account aggregation is working fine in one of the environments and not in lower environment anything with specific to environment which could cause this?
@charan18
Is the data or target connected from prod and non-prod are both same , if not definitely this error would be because of the data that is being aggregated as mentioned above
I think some test data of accounts which are larger than expected data size within IIQ, also are both your IIQ environments have properties related to link, managed attribute and other objects.
