Delete functionality is not working

Question

Hi
I have two EOs on two base tables  PO_REQUISITIONS_INTERFACE_ALL  and PO_INTERFACE_ERRORS and i have one VO having both EOs attached and have the sql query in the VO as below. I attached this VO in the AM. I have a page having regions style as 'query' and construction mode as 'autoCustomizationCriteria' and in that page i have two regions one is search region and another is results region. In the results region i have a button called 'Delete' and my functionality is when ever i click on Delete i am expecting the records should be deleted in both tables. But when i click on delete record is getting deleted only from PO_INTERFACE_ERRORS table not from PO_REQUISITION_INTERFACE_ALL table. Please let me know what needs to be done to fix this issue. I am also placing the CO and AM code below

Answer 1

Thanks..I changed and unchecked the 'Reference Flag' for Interface Lines VO while adding EOs in VO and it worked as it is deleting the record in Interface Lines Table also. But here i am getting one more issue on specific scenario.
My design of this development is as follow...
1. Search Page in which users give some search criteria and results will be displayed in the results region on the same page. For each results record I have two buttons like 'Update' and 'Delete' so that users can delete the record or can update the record. For update i created a one more page where users can able to edit and save the data.
Suppose I have one record in interface lines table and two records in error tables.When users given the search criteria and hit enter they found two records for same interface line. It means i have two records in error table and one record in interface table and both tables have same transaction id. So here user first try to update one record and it is working. After update he try to delete a record then I am getting below error. Please note that I am not getting this error when if i directly delete the record with out doing any update before delete.
Unable to perform transaction on the record.
Cause: The record contains stale data. The record has been modified by another user.
Action: Cancel the transaction and re-query the record to get the new data.
