    Knowledge on the working of the ENQUIRY

    When information is required for more than one T24

    application (which cannot be linked in the ENQUIRY

    application) When complex calculations and conditions are

    required and involves more than one T24 application

    Why NOFILE Enquiry ?

    File 1 File 2 File 3 File 4

    Routine

    No connection between Files cannot be linked in ENQUIRYComplex calculations that are not supported by the ENQUIRY application

    Setting up the ENQUIRY Application

    ENQUIRY : FILE.NAME Field - Mandatory

    This case - Requires more than one Application

    Use logical file name

    Define it in STANDARD.SELECTION

    No FILE.CONTROL Validation Error in SS

    Start STANDARD.SELECTION ID with NOFILE(Will not check for FILE.CONTROL record)

    Now use in Enquiry FILE.NAME

    Setting up the ENQUIRY Application

    STANDARD.SELECTION record requires a field

    Create a logical field

    How does the field get data?

    Write a routine and attach it to the logical field

    User need selection fields ?

    Define Selection type fields

    A bank requires a report in the following format.

    Customer Report

    Date : User :

    Customer Number :

    Account No Total Fwd Cr Total Fwd Dr Total Cr Int Total Dr Int

    XXXXXX XXXXXX XXXXXX XXXXXX XXXXXX

    XXXXXX XXXXXX XXXXXX XXXXXX XXXXXX

    XXXXXX XXXXXX XXXXXX XXXXXX XXXXXX

    A customer, at any point in time, may want to know the total of his

    Forward credit movements (Money that is due to the customer at a future date)

    Forward debit movements (Money that the customer is liable to pay at a futuredate)

    Accrued interest that is due to the customer (total)

    Accrued interest that the customer is liable to pay (total)

    NOFILE Enquiry Example

    9/2507 January 2005

    CUSTOMER.ACCOUNT To obtain the list of accounts for a

    particular customer

    ACCT.ENT.FWD To obtain the forward STMT.ENTRY Ids for

    an account of a customer

    STMT.ENTRY To obtain the details of the STMT.ENTRY

    record

    ACCR.ACCT.CR To obtain accrued credit interest

    ACCR.ACCT.DR - To obtain accrued credit interest

    Files To Be Used

    Solution 1 - Algorithm

    For the customer number supplied, extract record from CUSTOMER.ACCOUNT

    AC1FMAC2FMAC3FMAC4

    Read ACCT.ENT.FWD with the Account ID

    FST1FMFST2FMFST3

    Read STMT.ENTRY with the STMT.ENTRY ID

    AcIdFMCoCodeFMLCYAmtFMTranCodeFMCusIDFM.

    Extract the local currency amount and check if > than 0

    If > 0 then Future Cr Mov += Future Cr Mov else

    Future Dr Mov += Future Dr Mov

    Extract the next ID and process

    All F STMT

    entries have

    beenprocessed

    Solution 1 - Algorithm

    Read the ACCR.ACCT.CR file with the Account ID

    Total Credit Interest += Total Interest

    Read the ACCR.ACCT.DR file with the Account ID

    ENQUIRY Record

    Using this we can access eachline of information stored in the

    return variable. The values

    are separated by * and each

    set is separated by an FM

    This is the method used to extract

    the values returned from the routine

    Summary

    A NOFILE enquiry uses a routine to access more than one

    application to display information required by the user.

    A STANDARD.SELECTION record must be created, withan ID NOFILE.xxxxxxx for NOFILE enquiry to eliminate

    the FILE.CONTROL validation error in T24

    A STANDARD.SELECTION record created for NOFILE

    enquiry purposes can have logical fields defined in it.

    Routine type fields These fields will have user type R

    Selection type fields These fields will have user typeS

    Summary (Cont.)

    Selection fields defined, can be used within the routineusing the COMMON variables D.FIELDS andD.RANGE.AND.VALUES defined in

    I_ENQUIRY.COMMON

    A routine written for NOFILE enquiry purposes shouldreturn one parameter

    The ENQUIRY application uses the ID of the STANDARD.SELECTION in the FILE.NAME field

    F ,, - is used to extract thedata in the ENQUIRY
