Top Oracle Apps Technical Interview Questions

Q – 1 How to move the one file from one instance to another instance? And your scripts also?

Ans- Using FNDLOAD commands, which creates.ldt files and import those .ldt files in new instance using same command.

Q – 2 What is instead of trigger in where we will use?

Ans- Instead of triggers are the procedures that execute in place of Data Manipulation language (DML)statement on a table.

for example, if i have INSTEAD-OF-UPDATE Trigger on TableA,and i execute an update statement on that table,the
code in the INSTEAD-OF-TRIGGER will be executed instead of the update statement that I executed.

Q – 3 There are set of records to be processed from staging table into interface table. If one record fails the entire set of data should be rejected?

Ans- we can use rollback operation in exception block

Q – 4 How to Create a purchase order without a requisition?

Ans- We can create po three ways
(1)required sheet->requisition->RFQ->Quotation->po
(2) required sheet->requisition->po
(3) required sheet-po(with out requisition for po)

Q – 5 i have 3 parameters like p1,p2,p3. In p1 i have 2 parameters like a,b.if pass parameter a p2 should be enable and p3 should be disable then if pass parameter b the vice versa?

Ans- you can create two more dummy parameters(like p2_dummy,p3_dummmy ) and set display property to no.

now set the default value for p2_dummy as “decode (p1,’a’,’Y’,null) in the same way for p3_dummmy.

now in the valueset for p2 use where $FLEX$.p2_dummy =’Y’ and similarly for p3.

Q – 6 Tell me how to find the custom directory in front end?

Ans- From Application Developer responsibility, navigate to Application –> Register. Query for the custom application
name. The value in the field Basepath, is the OS system variable that stores the actual directory info.

Q – 7 Suppose for report i have to parameters those are from_date and to_date, so to_date should be greater when compare to from_date, if we are giving to_date is less then it must shows some error how we will make?

Ans- while defining Parameters you can set range option(in concurrent prog parameters window).
Select low for from_Date and high for to_Date.Then it will not allow for from_date > to_date.

Q – 8 What is the difference between request group and request security group in oracle apps?

Ans- Request group is where the concurrent programs are attached to which internally make them available under a
responsibility that the request group is attached to. If request groups won’t be there the program will not be
visible to the user who has a responsibilty attahced.
Data group is nothing but the data base user details with oracle apps connects UI to DB

Q – 9 Explain what are the tables of auto invoice?

Ans- RA_INTERFACE_LINES_ALL ,
RA_INTERFACE_DISTRIBUTIONS_ALL ARE THE TWO INTERFACE TABLES
MAINLY USED BT AUTOINVOICE.

FURTHER DATA READ FROM THESE TABLES WILL BE INSERTED INTO
RA_CUSTOMER_TRX_ALL , TA_CUSTOMER_TRX_LINES_ALL ,
RA_CUST_TRX_LINE_GL_DIST_ALL , AR_PAYMENT_SCHEDULES_ALL
AFTER VALIDATING.

Q – 10 Tell me where we find the status of order information?

Ans- Order header status is in oe_order_headers_all table reference with flow_status_code column and order line status would be oe_order_lines_all table reference with flow_status_code column.

Q – 11 What are the error tables in OM?

Ans- In Order ManagementOM) Error Tables are as follows

1.OE_EXP_INTERFACE_ERRORS
2.OE_UPGRADE_ERRORS

Q – 12 What is back order in OM?

Ans- There are few reasons that a scheduled order could be backordered during pick release process.

1. In-sufficient onhand
2. Order might be put as ‘Pick release hold’
3. If it’s a lot controlled item being involved then some of the factors will be checking at picking rule setup (like Lot- expiration date, etc) and tured to ‘Backordered’ incase the criteria does not meet.

Q – 13 What is pick selection list generation report?

Ans- shiping >>release sales order>>release sales order after releasing sales order

after executing release sales order automatically 3 concurrent programs will run

one of the conc prg is pick selection list the output of conc prg tells what orders has been booked

Q – 14 Do you know where we can check the status of po?

Ans- in po_headers_all authorization_status coloumn is their we can find through this coloumn
select distinct authorization_status from po_headers_all

Q – 15 What is count(*) from po_vendors(any table)? What does it do and
What is count(1) from po_vendors(any table)?
What is count(0) from po_vendors(any table)
the out put is same what is the difference?

Ans- Result if count(*), count(1), count(0) will be same.

Howevenr,

When we use count(*) then first oracle query executer gets all the rows in buffure cache, including all column and then counts all the rows. this will impact with less performance.

select count(1) or count(0)
This reduces unwanted I/O by selecting just ‘1’ against all the rows.

Best practice to getting rowcount of table is

select count(rowid) from table_name;

Q – 16 Do you know is it possible to run the interface without using oracle apps?

Ans- The Oracle standard interface code stays in the oracle apps database in the form of PL/SQL routines. Without the
database up and running, we can not run the interface code.
After all why do we run the interface, when the oracle apps is not available.

Q – 17 Tell me how to debug the report?

Ans- Set the profile option Concurrent: Debug Level to 5.
Run the report and get the debug log.
