ORA-20001：Posting Error Caused by Accounting Sequence

When we executed the posting process, the following error was displayed:

>> glpsqn() 07-JUL-2026 09:52:55PERF0005: Oracle error detected in function glpsqn() - ORA-20001:ORA-06512: at "FUSION.APP_EXCEPTION", line 61ORA-06512: ...PPOS0002: Posting terminated with irrecoverable errors.

Before this issue occurred, we modified an existing unused Accounting Sequence Version by changing its Name, Initial Number, Start Date, and End Date.

After making these changes, we created a journal with an accounting date that falls within the effective date range of the modified Accounting Sequence Version. However, the journal failed to post with the error shown above.

Could you please advise on the cause of this issue and how to resolve it? Any guidance would be greatly appreciated.
