ORA-01652: unable to extend temp segment in FUSION_TEMP

Q: How do I fix "ORA-01652: unable to extend temp segment in FUSION_TEMP" in Oracle Fusion?

1. Rerun with a smaller bite: a tighter cost cutoff date or narrower run scope 2. If it recurs at normal volumes, raise an SR with the request id, capacity is cloud-ops territory

Error code: ORA-01652

The run was so large it outgrew the database's temporary workspace mid-flight. Nothing is wrong with your data, the bite was too big for the plate.

Root cause

Volume/performance event: the run exceeded temp space.

How to fix it

Rerun with a smaller bite: a tighter cost cutoff date or narrower run scope
If it recurs at normal volumes, raise an SR with the request id, capacity is cloud-ops territory

Where to go in Fusion

Cost Accounting work area, Create Cost Accounting Distributions (the cost processor)
Navigator, Tools, Scheduled Processes
