R12: Invoice Actions: Troubleshooting Tax errors: 'User-Defined exception', 'An unexpected Error has occurred', 'A mandatory constraint to generate unique...violated' and others (Doc ID 1313644.1)

Last updated on JULY 08, 2020

Applies to:

Oracle Payables - Version 12.0.1 to 12.2.6 [Release 12.0 to 12.2]
Information in this document applies to any platform.
Payables Invoices Entry form - APXINWKB
Payables Batch Validation Program - APXAPRVL


Purpose


This article will help you solve most unhandled exceptions in the integration between Payables and eBTax (old version of this article is still available here <Note 1365130.1>, as of Oct-2011 it is no longer maintained).

Several of the scenarios in this document have had different root causes since R12 introduction (e.g: ZX_LINES_SUMMARY_U1 constraint violated has had numerous causes), this article provides the last solution available which includes all previous ones.

How to find your scenario

The user interface (e.g: APXINWKB) or the Batch Validation Process (APXAPRVL) post generic errors whenever an unhandled exception occurs in the Tax Engine. Example:

Unexpected error occurred during Tax Calculation.
Exception: User-Defined Exception
Please correct the problem or contact your System Administrator.


The underlying causes however, are varied. FND Debug Logs (<Note 458371.1>) provide detail to the procedure level allowing for a better identification of the underlying issue.

Whenever possible generate FND Debug Logs and scan it for the keywords in bold under the column "Detailed error" in the troubleshooting section below. You will most likely find a direct match.

Whilst Errors messages in the user interface, APXAPRVL or FND Logs vary between point releases. Ultimately FND Logs will contain keywords describing the error exactly (e.g: ORA-00001 and <package>).

 

Generic errors you will first observe in the UI or APXAPRVL

 

Note that:
  1. APXAPRVL will not display the messages equally, rather they will be prefixed by "MSG-00000: When Others:" (e.g: MSG-00000: When Others:User-Defined Exception)
  2. FND Logs will display the messages with some differences and in conjunction with ORA-20001, APP-SQLAP-10000, and others. Example: "APP-SQLAP-10000: A mandatory constraint to gene occurred in", which in essence is the same as "Exception: A mandatory constraint to generate unique summary tax line is violated with error ORA-00001" in the UI.
  3. Messages can vary across different point releases of R12 in their text, but not their keywords.
  4. Use the bold keywords under the column "Detailed error" in the troubleshooting section below to identify the exact one within the FND Debug Log.
