Oracle Apps interview questions
Question: You are told that the certain steps in the Oracle Apps Form/Screen are running slow, and you are asked to tune it. How do you go about it.
Answer: First thing to do is to enable trace. Preferably, enable the trace with Bind Variables. This can be done by selecting menu Help/Diagnostics/Trace/”Trace With Binds and Wait”
Internally Oracle Forms issues a statement similar to below:-
alter session set events='10046 trace name context forever, level 12' ;
Enable Trace with Bind Variables in Apps
This will enable the trace with Bind Variable values being shown in the trace file.
The screen in Oracle Apps will also provide the name of the trace file which is located in directly identified by
select value from v$parameter where name like '%us%r%dump%'
Doing a tkprof with explain plan option, reviewing plans and stats in trace file can help identify the slow performing SQL.
Question: What is the difference between running Gather Stats and “Program – Optimizer[RGOPTM]” in Oracle General Ledger?
Answer: “Gather Stats” will simply gather the stats against existing tables, indexes etc. However Gather Stats does not create any new indexes. But “Program – Optimizer[RGOPTM]” can create indexes on GL_CODE_COMBINATIONS, provided accounting segment has the indexed flag enabled,
Question: You have written a piece of code in POR_CUSTOM_PKG for Oracle iProcurement, but its not taking any effect? What may be the reason?
Answer: Depending upon which procedure in POR_CUSTOM_PKG has been programmed, one or more of the below profile options must be set to Yes
POR: Enable Req Header Customization
POR: Enable Requisition Line Customization
POR: Enable Req Distribution Customization
Question: What is the key benefit of punching out to suppliers catalogs rather than loading their catalogs locally in Oracle iProcurement?
Answer: Punchout has several advantages like, Catalogs don’t need to be loaded locally saves space on your system. You can get up-to-date list of catalogs by punching out and also you get the benefit of up-to-date pricing information on vendor items.
Question: Does oracle have a test environment on exchange?
Answer: http://testexchange.oracle.com
Question: Does Oracle Grants use its own schema or does it uses Oracle Project Accounting schema?
Answer: Although Oracle Grants has its own schema i.e. GMS, it reuses many of the tables with in Oracle Projects Schema like PA_PROJECTS_ALL, PA_EXPENDITURE_ITEMS_ALL, PA_EXPENDITURE_TYPES etc.
Question: How to make an Oracle Report Type concurrent program produce an excel friendly output?
Answer: Comma can be concatenated between the column values, however a better option is to create tab delimited file, as it takes care of commas within the string.
For this, use SQL similar to below in the report
select 'a' || chr(9) || 'b' from dual;
Question: What are the settings needed for printing bitmap reports?
Answer: Get your DBA to configure two files i.e. uiprint.txt & default.ppd
For details, refer to Metalink Note 189708.1
Question: For a PL/SQL based concurrent program do you have to issue a commit at the end?
Answer: The concurrent program runs within its own new session. In APPS, the default database setting enforces a commit at the end of each session. Hence no explicit COMMIT is required.
Question: What is the best way to add debugging to the code in apps?
Answer: Use fnd_log.string , i.e. FND Logging. Behind the scenes Oracles FND Logging uses autonomous transaction to insert records in a table named fnd_log_messages.
For example
DECLARE
BEGIN
fnd_log.STRING(log_level => fnd_log.level_statement
,module => 'xxxx ' || 'pkg/procedurename '
,message => 'your debug message here');
END ;
Three profile options effecting FND Logging are
FND: Debug Log Mode
FND: Debug Log Enabled
FND: Debug Log Module
Question: If you wish to trigger of an update or insert in bespoke table or take some action in response to a TCA record being created or modified, how would you do it? Will you write a database triggers on TCA Tables?
Answer: There are various pre-defined Events that are invoked from the Oracle TCA API’s.
TCA was Oracle’s first initiative towards a fully API based approach, which means the screen and the processes all use the same set of APIs for doing same task.
In order to take an action when these events occur, you can subscribe a custom PL/SQL procedure or a Custom Workflow to these events. Some of the important TCA events are listed below:-
oracle.apps.ar.hz.ContactPoint.update
oracle.apps.ar.hz.CustAccount.create
oracle.apps.ar.hz.CustAccount.update
oracle.apps.ar.hz.CustAcctSite.create
oracle.apps.ar.hz.CustAcctSite.update
oracle.apps.ar.hz.CustAcctSiteUse.create
oracle.apps.ar.hz.CustAcctSiteUse.update
oracle.apps.ar.hz.Location.create
oracle.apps.ar.hz.Location.update
oracle.apps.ar.hz.Organization.create
oracle.apps.ar.hz.Organization.update
oracle.apps.ar.hz.PartySite.create
oracle.apps.ar.hz.PartySite.update
oracle.apps.ar.hz.PartySiteUse.create
oracle.apps.ar.hz.PartySiteUse.update
oracle.apps.ar.hz.Person.create
oracle.apps.ar.hz.Person.update
Question: In Oracle OA Framework, is the MDS page/document definition stored in database or in the file system?
Answer: The MDS document details are loaded into database, in the following sets of tables.
JDR_ATTRIBUTES
JDR_ATTRIBUTES_TRANS
JDR_COMPONENTS
JDR_PATHS
The Document is loaded via XMLImporter, as detailed in XMLImporter Article
Question: In a Oracle Report data group, you have a “data link” between two queries. How do you ensure that the data link is made Outer Joined?
Answer: The data link is an Outer Join by default.
Question: How does substitution work in OA Framework?
What are the benefits of using Substitution in OA Framework?
Answer: Based on the user that has logged into OA Framework, MDS defines the context of the logged in user. Based upon this logged in context, all applicable personalization are applied by MDS. Given that substitutions are loaded as site level personalizations, MDS applies the substituted BC4J objects along with the personalizations. The above listed steps occur as soon as Root Application module has been loaded.
The benefit of using Substitution is to extend the OA Framework without customization of the underlying code. This is of great help during Upgrades. Entity Objects and Validation Objects can be substituted. I think Root AM’s can’t be substituted given that substitution kicks off after Root AM gets loaded.
Question: In OA Framework, once your application has been extended by substitutions, is it possible to revert back to remove those substitutions?
Answer: yes, by setting profile option “Disable Self-Service Personal%” to Yes, keeping in mind that all your personalizations will get disabled by this profile option. This profile is also very useful when debugging your OA Framework based application in the event of some error. By disabling the personalization via profile, you can isolate the error, i.e. is being caused by your extension/substitution code or by Oracle’s standard functionality.
Question: How can you import invoices into Oracle Receivables?
Answer: You can either use AutoInvoice by populating tables RA_INTERFACE_LINES_ALL, RA_INTERFACE_DISTRIBUTIONS_ALL & RA_INTERFACE_SALESCREDITS_ALL.
Alternately you may decide to use API ar_invoice_api_pub.create_single_invoice for Receivables Invoice Import.
Question: How do you setup a context sensitive flexfield
Answer: Note: I will publish a white paper to sho step by step approach.
But for the purpose of your interview, a brief explanation is…a)Create a reference field, b) Use that reference field in “Context Field” section of DFF Segment screen c) For each possible value of the context field, you will need to create one record in section “Context Field Value” ( beneath the global data elements).
Question: Does Oracle iProcurement use same tables as Oracle Purchasing?
Answer: Yes, iProcurement uses the same set of requisition tables as are used by Core Purchasing.
Question: What is the name of the schema for tables in tca
Answer: AR (at least till 11.5.10, not sure about 11.5.10).
Question: Are suppliers a part of TCA?
Answer: Unfortunately not yet. However, Release 12 will be merging Suppliers into TCA.
Question: What is the link between order management and purchasing
Answer: Internal Requisitions get translated into Internal Sales Orders.
Question: How would you know if the purchase order XML has been transmitted to vendor, looking at the tables.
Answer: The XML delivery status can be found from a table named ecx_oxta_logmsg. Use the query below
SELECT edoc.document_number
,decode(eol.result_code, 1000, 'Success', 'Failure') AS status
,eol.result_text
FROM ecx_oxta_logmsg eol
,ecx_doclogs edoc
,ecx_outbound_logs eog
WHERE edoc.msgid = eol.sender_message_id
AND eog.out_msgid = edoc.msgid
ORDER BY edoc.document_number
Question: You have done forms personalization, now how will you move it from one environment to another?
Answer: Use FNDLOAD. For examples visit FNDLOAD Article
Question: What are the key benefits of forms personalization over custom.pll?
Answer:
-->Multiple users can develop forms personalization at any given point in time.
-->It is fairly easy to enable and disable forms personalizations.
-->A programmer is not required to do simple things such as hide/disable fields or buttons.
-->Provides more visibility on customizations to the screen.
Question: Tell me some limitations of forms personalization when compared to CUSTOM.pll?
Answer:
-->Can't create record group queries, hence can’t implement LOV Query changes.
-->Can't make things interactive, i.e. can’t have a message box that gives multiple choices for example Proceed or Stop etc.
Question: Give me one example where apps uses partitioning?
Answer: WF_LOCAL_ROLES
Question: Give me one example of securing attributes in iProcurement.
Answer: You can define Realm to bundle suppliers into a Category. Such realm can then be assigned to the User using Define User Screen. Security Attribute ICX_POR_REALM_ID can be used. By doing so, the user will only be made visible those Punchout suppliers that belong to the realm against their securing attributes.
Question: Can you send blob attachments via workflow notifications?
Answer: Yes, you can send BLOB Attachments.
