R12: Create Accounting in error due to older files

File this one away for reference if you are upgrading to R12, or if you are applying some patches, and your Create Accounting program starts giving you ORA-00001 errors.  My Oracle Support note "Create Accounting Program Ending In Error:An internal error has occurred in the program xla_je_validation_pkg.populate_segment_values. ORA-00001: unique constraint (XLA.XLA_AE_SEGMENT_VALUES_U1) violated." from document ID 1902705.1 is directly on point with the files, versions, and patch which will resolve this.

If this helps you, please let me know so I can look for more of these types of articles in the future!
