And i would suggest that you better read through the Peoplebooks for Application Engine programs so that you can better understand the facts about having PROCESSINSTANCE as a keyfield. Also, remember that an AE can have multiple State Records but Only one can be a default state record. Again, you may need to go thru the peoplebooks. Your User ID and/or Password are invalid.

State Record In Peoplesoft
1.It is a PeopleTool and It is used to develop batch programs oronline programs that perform the backed processing against the data.
2.It consists of the 2 distinct components .They are
Designer->Consists of the batch programs.
Run time Environment->To run and monitor the programs.
3.A program is a set of SQL statements.
4.It does not generate SQL or PeopleCode, but it executes SQL or PeopleCode asa part of program.
5.It is designed for batch processing where data must be processed without userinteraction.
6.AE resides on database server.
APPLICATION ENGINE PROGRAM ELEMENTS:
1.PS AE consists a set of processes to execute a given task and made up ofseveral elements.They are
i) Sections
It is a set of ordered steps that gets executed as a part of the program.Theexecution of the program starts with the section defined as MAIN.
ii) Steps
Steps are the smallest unit of the program that can be commited within aprogram.It is used to execute the a peopleCode
command or log a message with the step.When the section gets called, its stepsexecute sequentiately.
iii) Actions
Multiple actions can be within a step.There are 5 multiple actions they are
DO ACTIONS:
Do actions contain a SQL statements taht is designed to return the results onwhich subsequent actions depend.
It is equvalent to a COBOL perfrom statement.There are 4 types of Do actios theyare:
1)Do While 2)DO When 3)Do Select 4)Do Until.
SQL AND CALL SECTION ARE MUTUALLY EXCLUSIVELY ACTION WHICH CANNOT BE PERFORMEDONCE AT ATIME COZ IT CAUSES DEADLOCKS
SQL:
It contain a single SQL statements.There are 4 types of SQL statements.They are
1)Update 2)Delete 3)Insert 4)Select

1)Update 2)Delete 3)Insert 4)Select
PeopleCOde:
It provides an excellent way to build dynamic SQL, perform simple if/elseedits,set defaults and other operations that
don't require a trip to the database
Log Message:
Call Section:
It is used to call and insert an action in the progaram or outside program.
iv) State Records
It is a PeopleSoft Record that must be created and maintained by theApplication Engine developer.
This record defines the fields a program uses to pass values from one action toanother.
It can be either a Physical record or a work record, any no of sate records canbe assosiated with a program.
Physical state records must be keyed by process instance.
APPLICATION ENGINE PROGRAM TYPES:
There are 5 types of Application Engine Programs.They are.
1.Standard->Normal entery point program.
2.Upgrade Only->used in PS Upgrade utilites.
3.Import Only->used by PS import utilites.
4.Daemon Only->A type of program which is used a daemon Process.
5.Transform Only->used to support Extensible stylesheet languageTransformations(XSLT).
DAEMON PROGRAM TYPE:
1.PS AE provides a daemon process called PSDAEMON, that runs continously whenPS Process Scheduler is running and it is intended for running jobs.
2.It consists of a predefined set of conditions as events.When PSDAEMONschedules a process to handle an event when the conditions are true.
3.It allows only PS AE tracing at the step and SQL levels
META-SQL
1.Meta-SQL is a set of predefined terms designed to replace RDBMS syntax.
2.PS meta-SQL enables us to dynamically generate portions of SQL code.(EX;--2join 2 tables based on their common keys)
3.%select->It is ued to insert values of varibles in to sate record.
4.%bind->It is used to get values.
Peoplesoft Dc
SQLEXEC();
By using the SQLEXEC() function we can do the data manipulation (Insert,Updateand Delete).
Example:
SQLEXEC('select * from PS_JOB whereX.EMPID.vlaue=:1',abc,&emplid1')
The main draw back using this SQLEXEC() function is 'It will return onlyone value at a time'.
Note:-for more in detail draw backs about SQLEXEC,please go through the otherpost Reasons why PeopleSoft does not recomd SQLEXEC()'
Sate Records:
It is a working storage.
It is a physical record or derived work record
It passes values from section to section ,Action to Action and step to step.
We can use 'N' no of state records in a program.
It consists of Runcontrol ID and Process Instance ID.
It it is a physical record then process Instance ID must be keyed.
It maintains temporary data in AE programs for online processing.
State Record Properties
General
-------
It is used to select any sate record from the list
Temp Tables
-----------
1.Select the temp tables tab.
2.It is used to get a temporary record.
3.When we enter any of the wild card character or the table full name and Clickon get list.Then it displays all the records containing temporary tables.
4.Select the necessary temporary table and click o add in to the list.
5.We can remove a particular temporary table by selecting it and click onremove.
6.Instance count is used to enter the no.of physical tables to be created foreach dedicated table for this program during the SQL Build procedure inPeopleSoft Application Designer.If we want to any program to run for 3 timesthen we should specify in the instance count.
7.If we select base version then it uses the temporary tables.
8.If we select Abort then the program exists with an error message.
Advanced Tab
------------
1.Disable Restart
2.Application Library
3.Batch only
4.Messsage Set
5.Program Type (STD,Upgrade,Import,Daemon,Transform)
Restating an AE program
The Key feature of AE is Restart.
Sate record should be a physical record.When the system is processing a hugeamount of data (batch processing) and if there
occurs any failure through the environment then the restartable logic comes into picture.The cursor directly comes in to the checkpoint where the commit isset upand restarts the program from that point.
We can restart the program from the process request page.
AERUNCONTROL record saves all the information that is required for a program torestart.
File Layout's
1.It is used for file processing using INBOUND and OUTBOUND process
2.A File layout is acollection of records.
3.Works with hierarchical and non-hierarchical data
4.stored with _FLT
5.It enables us to do the following
-->Export and Import the data.
-->It uses Batch Process to perform large amount of data import and export.
-->There are 3 types of file formats.They are CSV,XML,FIXED.
6.It also facilitates to provide the transaction between PS systems and 3rdparty systems
Inbound Program
Reading from a FALT file and writing in to database
-->Open the flat file in READ mode
-->Read each and every line in a flat file and put them in a string
-->Split the data with separators and put it in an array
-->Insert the values in to the record by matching the field values in torecord.
Example:
Local record &rec
&myfile=getfile('c:/documents/abcd.txt','R',%filepath_absolute);
&arr=createarrayrept(',0);
&rec=createrecord(record.EMP_TBL);
If &file.open() then
while &file.readline(&str);
&arr = split(&str,',');
&rec.EMP_ID.value = &arr[1];
&rec.EMP_NAME.value = &arr[2];
&rec.EMP_AGE.value = &arr[3];
&rec.insert();
End-while;
end-if;
&myfile.close
Outbound Program
Writing from a Database to flatfile
-->Open the flat file in WRITE mode.
-->Use the %SELECT to select all the record field values.
-->Put the field values in a dummy record.
-->By using the dummy record field value write the files to FLAT file usngWRITELINE.
Example:
&myfile=getfile('c:/documents/abcd.txt','W',%filepath_absolute);
&myfile.open('c:/documents/abcd.txt','W');
For i=1 to5;
&myfile.writeline('HI welcome to PS world');
end-for;
&myfile.close
A sample code to read a file using file layouts and insert data read into arecord
Local File &MYFILE;
Local Record &REC;
Local array of string &ARRAY;
Local string &FILE_DIRECTORY, &FileName;
&FileName = 'MY_FILE_NAME.txt';
&FILE_DIRTORY = '/MYDIRECTORY/'
/*open file for reading*/
&MYFILE = GetFile(&FILE_DIRECTORY | &FileName, 'R',%FilePath_Absolute);
/*create record object*/
&REC = CreateRecord(Record.MY_RECORD);
&ARRAY = CreateArrayRept(', 0);
/*check if file is open*/
If &MYFILE.IsOpen Then
/*The SetFileLayout method is a file layout method. It associates a specificfile layout definition with the file object executing this method, providingeasy access to rowset data.(PeopleBooks)*/
If &MYFILE.SetFileLayout(FileLayout.FILE_LAYOUT_NAME) Then
/*read line into &STRING*/
While &MYFILE.ReadLine(&STRING);
&ARRAY = Split(&STRING, ',');
For &I = 1 To &REC.FieldCount
&REC.GetField(&I).Value = RTrim(LTrim(&ARRAY [&I]));
End-For;
/* do additional processing here for converting values */
&REC.Insert();
/*count rows inserted into record*/
&COUNT = &COUNT + 1;
End-While;
Else
/* do error processing - filelayout not correct */
End-If;
Else
/* do error processing - file not open */
End-If;
We can run the AE in 3 way's
1.Application Designer -->RUN
2.Command Line -->PSAE.EXE
3.Process Scheduler.
Order of events in Application Engine
1.Do When
2.Do While
3.Do Select
