Import Application Fails With Error ORA-20001: WWV_FLOW_API.ERR_REGION_COLUMN_CREATE

(Doc ID 2304142.1)

Last updated on SEPTEMBER 08, 2017

Applies to:

Oracle Application Express (formerly HTML DB) - Version 5.1.0 to [Release 5]
Information in this document applies to any platform.


Importing an application fails with error: 

Execution of the statement was unsuccessful. ORA-20001: WWV_FLOW_API.ERR_REGION_COLUMN_CREATE ORA-02291: integrity constraint (APEX_050100.REGION_COL_LOV_FK) violated - parent key not found



It appears that if an Interactive-Grid page is copied from another application and then the application is exported and assigned a new APP_ID, the error is triggered.
