I've seen this error - not often, but not only a "one time" thing - in an Oracle EBS implementation:
INC_04050702: The underlying data for this insight is being updated, Cannot get read lock on Resources EBS_PA.PA_PROJECTS_ALL._@JOIN@_EBS_FIN_COMMON_alias_ZX_RATES_B_PurchasingRate
which runs counter to my understanding of how Incorta works.
I thought ( think ) that Incorta writes temp files during the loading process and then swaps them out ( full load ) or adds the increment ( incremental load ) specifically so that analysts can keep analyzing during the load process.
Looking for a correction to my thinking and/or some insight into what might be the underlying cause of the referenced error.
