Error "Each row in the Query Result Columns must be mapped to a unique Query Attribute in Mapped Entity columns" while extending a VO

I was trying to extend the seeded iProcurement VO “ReqsApprovalsVO” with out adding any custom attributes.


When I clicked “Next” button on the Step 4/7 (Attribute Mappings), I hit this roadblock which keeps saying “Each row in the Query Result Columns must be mapped to a unique Query Attribute in Mapped Entity columns” and does not let me extend the VO after this.

I thought of several reasons which could be causing this error. I thought it had something do with the file version of the seeded VO I am trying to extend or it could be due to the jDeveloper version I am using.
I ruled out all the possibilities one by one including the jDeveloper issues. Then I looked in metalink and one of the notes gave me a little clue which would solve my issue.

Source: Metalink Note: 1524622.1

I went back to the seeded VO to see if any of the attributes are having this issue. Right Click on “ReqsApprovalsVO”
à Edit ReqsApprovalsVO
I found this attribute OrgId which is “Mapped to Column or SQL” and has the Query column as “OrgId”

When I verified the SQL Statement for this VO, OrgId attribute has been pulled as “Org_Id” in the query which is not same as “OrgId” and this explains me why the error has been occurring when I am trying to extend the VO.

To resolve the issue, I changed the OrgId to ORG_ID in the seeded VO and was able to extend the VO there after.

Upload or Download Oracle Workflows using WFLOAD Command Line Utility

Oracle Workflows are Database Applications whose definitions are stored in different Database Tables.
We can easily Upload/Download these definitions of the Workflows to the flat files using WFLOAD command line utility.
Workflow files are stored under <Application Top>/patch/115/import/US/ (Ex: PO_TOP/patch/115/import/US/powfpoag.wft)

To Upload
--------------
WFLOAD apps/<apps_password> <Access_Level> Y <upload_mode> <file_name>.wft
Example: WFLOAD apps/appspwd 0 Y FORCE powfpoag.wft

To Download
--------------------
WFLOAD apps/<apps_password> <Access_Level> Y DOWNLOAD <file_name>.wft
Example: WFLOAD apps/appspwd 0 Y DOWNLOAD powfpoag.wft

Different UPLOAD modes used while uploading the WFT file to the database.

Basics about Profile Options

Profile Options are like Global Variables for Oracle Applications. They provide flexibility to Applications and how they work.

There are 2 types of Profile Options

1    1. System Profile Options
      2. User Profile Options

When logged in as System Administrator, the difference between System Profile and Personal Profile are to whom you are making the changes for.
To Navigate to System Profiles
System Administrator
à Profile à System

From the System Profile screen, you are making changes to the profile options at any level including personal/user

From the User Profile Screen, you are making changes to the profile option values for yourself /user(who logged in). To navigate to Personal Profile:
System Administrator --> Profile --> Personal

User Profile Option is also available for all the users through Edit à Preferences à Profiles




Oracle Data Security and its components


Data Security: Coordinating with Function Security, Data Security provides additional security on the data. It lets the administrators decide what are all the actions that users can perform on the data.
Data Security Policies can reflect access to 
a. All Instances : All instances of an object represents that all rows in the database related to that object. If you consider Purchase Order (PO) as an object and All Instances of PO means all the Purchase Orders in the database. 
b. Instance Set: Instance set of an object represents a set of the related instances of an object. In our Purchase Order as an object example, a set of Blanket Purchase Orders represent a set of Instances of the PO. 
c. A Specific Instance: This generally represents a single row in the database. It is usually identified by a Primary Key value for the object(Ex: PO Header Id)
