Ignore Pricing for Order Lines-Custom Hook

This is an enhancement to Oracle Advanced Pricing functionality and is released as a part of 11.5.10 and R12 releases. This functionality can be used to improve the performance of the system by avoiding lines from going through pricing engin if not required.

The Ignore Pricing custom hook provides users an opportunity to inform pricing engine to ignore such lines that could result in substantial performance gain

Implementing QP_custom_ignore.Ignore_itemline_for_pricing
If you intend to use ignore_itemline_for_pricing you must create a package body for qp_custom_ignore with the procedure ignore_itemline_for_pricing. Refer the package specification for further information on the package

Patches delivering the QP_CUSTOM_IGNORE.ignore_itemline_for_pricing functionality
Release 11.5.10 – Please apply patch 8203943
Release 12.0 - Please apply patch 8266809:R12.QP.A

How to incorporate the logic of viewing the concurrent request output from the custom form?

If the requirement is to incorporate the logic of viewing the concurrent request output from the custom form instead of viewing the output through standard view request form, apply the below approach.

1. Attach FNDCONC.pll file to the custom form.
2. In the WHEN-BUTTON-PRESS trigger of the object in the custom form call the following package
EDITOR_PKG.REPORT(req_id, save_output_flag);

Vendors with no Invoices

select segment1 VENDOR#,

vendor_name NAME,
vendor_site_code SITE_CODE,

from po_vendors vend,
po_vendor_sites_all sites,
ap_invoices_all inv
where vend.vendor_id = sites.vendor_id
and sites.vendor_site_id = inv.vendor_site_id(+)
and inv.vendor_site_id is null;

Fetch Profile values at different levels

This query will give the values of the profile option set at different level. Use the profile option name or user profile option name which you see in the front end.

SELECT user_profile_option_name,SUBSTR(e.profile_option_name,1,25) PROFILE
,DECODE(a.level_id,10001,'Site',10002,'Application',10003,'Resp',10004,'User') "Level"
,DECODE(a.level_id,10001,'Site',10002,c.application_short_name,10003,b.responsibility_name,10004,d.user_name) LValue
,NVL(a.profile_option_value,'Is Null') Value
,SUBSTR(a.last_update_date,1,25) UPDATED_DATE
FROM fnd_profile_option_values a
, fnd_responsibility_tl b
, fnd_application c
,fnd_user d
, fnd_profile_options e
, fnd_profile_options_tl f
WHERE 1=1
AND f.user_profile_option_name in ('&User_Profile_Name')
AND e.profile_option_id = a.profile_option_id AND a.level_value = b.responsibility_id (+)
AND a.level_value = c.application_id (+) AND a.level_value = d.user_id (+)
AND f.PROFILE_OPTION_NAME(+)=e.profile_option_name
ORDER BY e.profile_option_name;

Adding New Processing constraint in Order Management

Add New business constraint in the Processing Constraint form (Setup : Rules : Security)

Entity : Choose the entity on which the constraint needs to be applied.
Constraints Block : Define the action or the constraint.
Condition Block : Define the condition upon which the Constraint needs to be fired.
Applicable To Block : Define the responsibilities to which the constrain is applicable.

Validation Template : New template needs to be defined in the Validation template form before attaching the same to the Processing constraint. (Setup : Rules : Security)

Validation Template Type can be of 3 types : API, Workflow or Table
1. API - Type the custom PLSQL package in the Package field and the procedure within the package in the procedure field. The procedure needs to be declared as below

Procedure xx_procedure_name ( p_application_id IN NUMBER,

p_entity_short_name in VARCHAR2,
p_validation_entity_short_name in VARCHAR2,
p_validation_tmplt_short_name in VARCHAR2,
p_record_set_tmplt_short_name in VARCHAR2,
p_scope in VARCHAR2,
p_result OUT NOCOPY NUMBER ) IS

All the IN parameters are passed by the system internally. The OUT parameter accepts two results 1 (TRUE) or 0 (FALSE). Based on the result from the validation Template, the condition is true or false.

2. Workflow : Enter the Item Type, Process Name, Status and the Result expected for the condition to be TRUE.

3. Table Type : Specify the Column Name, the Validation Operator and the string to which the column value needs to be compared to.

Wrapping PL/SQL Source Code

Wrapping is the process of hiding PL/SQL source code. Wrapping helps to protect your source code from business competitors and others who might misuse it.

You can wrap PL/SQL source code with either the wrap utility or DBMS_DDL subprograms.

Guidelines for Wrapping
Wrap only the body of a package or object type, not the specification
Wrap code only after you have finished editing it.
Wrapped code cannot be unwrapped. To change wrapped PL/SQL code, edit the original source file and then wrap it again.

Limitations of Wrapping
Wrapping does not hide the source code for triggers
Wrapping is not a secure method for hiding passwords
Wrapping does not detect syntax or semantic errors

1. To run the wrap utility
wrap iname=input_file [ oname=output_file ]

2. DBMS_DDL.WRAP

Generating report using Java Concurrent Program

While browsing through a standard Cocurrent program, found a interesting and unusual way of generating report using Java Concurrent program.

Program Name : CLE: AP Purchasing Ledger Report
Short Name : CLEF224PVR
Java code called : JCP4XDODataEngine.java
Data template attached in Data Definition : CLEF224PVR.xml
RTF Template representing the design : CLEF224PVR.rtf

The java program calls the data template which has the main SQL query. This file is a xml file and it internally also refers to database package. Later this is processed with RTF template to generate the output. Besides check out the java program to know how to write into log file and access concurrent program parameters and other context values.

How to create a VPD (Virtual Private Database) Policy on a table or view in 10g

Standard Package DBMS_RLS can be used to add, delete, enable, disable, refresh VPD policies.

dbms_rls.add_policy('APPS','PO_HEADERS_V','accesscontrol_PO_HEADERS','system','f_policy_po,sec_relevant_cols=>'ORDER_AMOUNT',sec_relevant_cols_opt => dbms_rls.ALL_ROWS);

Parameter 1 - object owner
parameter 2 - Object Table/ View Name
Parameter 3 - Policy Name
parameter 4 - schema of the policy function
Parameter 5 - database function which returns a where clause as string (the function will have the logic to restrict the records to be fetched)
sec_relevant_cols - the column of which the data is restricted from viewing to the user
sec_relevant_cols - setting it to dbms_rls.ALL_ROWS would display all the rows to a user with blank data shown for the restricted column for the records which are non viewable.

How to add a column to LOV in OA Framework?

A. You extend the base view object, and add additional column to this view object's query
B. Using personalizations, add a new field to the specific LOV Page. This can be done by using "create new item" in OA Framework Personalizations.
C. Map the new field that was created above to view object column, by specifying the source view object and souce column.

How to remove substitution/extension to a VO object in OAF

There are three ways, but firstly you must understand the basics of how Oracle stores OA Framework substitutions. When you load the substitutions using jpxImporter, Oracle creates a site level personalization, which gets stored in the database. Now to rollback/remove/disable viewobject substitutions
Option A. Delete personalization, using jdr_util.delete_documents
Alternately use "Functional Administrator" responsibility to delete the personalization
Option B. Disable personalization that corresponds to substitution, again using Functional Administrator
Option C. Set profile "Disable personalization" to Yes at site level

The common thing about all three options above is that they all pertain to removal of personalizations that were created as result of view object substitution in OA Framework.

How to check standard VO Object has any extension?

Use the following query to find if there is any extension to a given VO Object. Give VO name as parameter to the query.

SELECT JA.* FROM JDR_PATHS JP, JDR_ATTRIBUTES JA
WHERE JP.PATH_DOCID = JA.ATT_COMP_DOCID
AND JP.PATH_NAME = 'VO_OBJECT_NAME'

In the attribute name column against customize column you would find the extensions.

How to extend OAF Controller

Steps to extend controller object to customize the same. 1. Open the controller class after decoding the same in Jdev.
2. Create a new class file by righclicking on the project.
3. Mention the name of the new extended class in Name. The new extended class package in the package. And the original controller class file package in the Extends.
4. After the custom logic is added in the newly extended controller, move the java file to the server, compile the file to generate the class file for the same.
 javac .java
5. Bounce the server.
6. Unlike VO and EO extensions, CO extension will not be called unless the same is mentioned in the OAF personalization. Enable the personalization.
7. Select "Complete View" and "Expand All" Option in personalization page.
8. Mention the extended controller file name in the personalization link of the component. Test now if the extended logic is reflected.
