Interface Programing thru ABAP

Question

Hi Abapers,
I have created LLD for one interface, but do not know how to convert it to actual coding.  Please help me out in same.  please help me in atleast as much points in which you can.
A) For standard price change:-
A.1) Update the pricing date:-
     VBKD-PRSDT = tomorrow’s date.
A.2) To update the price:-
  Part of standard function SD_BULK_CHANGE:-
[  RV45C = DYNPRO_FIELDS.
  CASE FUNCTION.
      WHEN 'MPRF'.
      CLEAR FLAG.
      CLEAR NEW_VBELN.
      CLEAR PREISFINDUNG.
      till endform.
1)     Select line within the new ZPRICE table
Where           VBAK.VBELN = ZPRICE.VBELN (Contract #)
VBAK.POSNR = ZPRICE.POSNR (Item#)
2)     Compare net price (NETPR) for that line within the ZPRICE table to the calculated tomorrow’s price determined in step 1 above.  If price is the same do nothing.  If price has changed delete previous entry and make a new entry.  If no entry is found in the ZPRICE table for a specific contract and item combination make a new entry.  Populate the new entry using the following logic.
     ZPRICE.VBELN = VBAP.VBELN (Contract #)
     ZPRICE.POSNR = VBAP.POSNR (Item #)
     ZPRICE. WAERK = VBAP.WAERK (Document Currency)
     ZPRICE.NETPR = VBAP.NETPR (Net Price)
     ZPRICE.MEINS – VBAP.MEINS (Item base unite of measure)
     ZPRICE.DATAB = Tomorrow’s Date
     ZPRICE.ERDAT = Today’s Date
3)     Select price condition records that were created today and have effective dates in the past
Select      KONH.KNUMH (Condition record number)
     KONH.DATAB (Valid-From Date)
Where      KONH.KVEWE = “A” (Usage = Pricing)
     KONH.KAPPL = “V” (Application = Sales/Distribution)
KONH.ERDAT = Today’s Date (Created on date)
KONH.DATAB < Today’s Date (Valid-From Date is in the past)
4)     Select customer menu’s associated with the retroactive pricing condition record
Select      VBAP.VBELN (Contract #)
     VBAP.POSNR (Item #)
Where     KONV.KNUMH = KONH.KNUMH (Condition record number)
VBAK.KNUMV = KONV.KNUMV (Document condition number)
VBAK.AUART = “ZMNU” (Document Type)
VBAP.POSNR = KONV.KPOSN (Item #)
5)     Select net price for contract line item within the new ZPRICE table
Select      ZPRICE.NETPR (Net Price)
Where      VBAK.VBELN = ZPRICE.VBELN (Contract #)
VBAK.POSNR = ZPRICE.POSNR (Item#)
Determine and compare the net price of the contract line item for each previous day until the net price no longer equals the net price within the ZPRICE table.  When complete, Use Function from which is used step A
6)     Within ZPRICE table change the effective date (ZPRICE.DATAB) to the last day the price equalled ZPRICE.NETPR.  In the above example the date would be 8/01/2006 since the price was different on 7/31/2006.
7)     Select all customer menu and item combinations that are associated with each customer pricing contact that have an associated output condition record in table – B504 (Customer Pricing Contact – PARNR)
Select           B504.PARNR (Contact #)
VBPA.VBELN (Contract #),
VBPA.POSNR (Item #)
Where           VBPA.PARNR = B504.PARNR (Contact #)
          VBPA.PARVW = “Z8”
          VBAK.AUART = “ZMNU”
Inner Join      VBAK.VBELN = VBPA.VBELN
Contact #     Contract #     Item #
50000     0040000010     10
50002     0040000010     20
50003     0040000021     10
50005     0040000010     10
50005     0040000021     20
8)     Per pricing contact determine if the price has changed for any contract and item combination assigned to that pricing contact. If price has changed, then trigger price change notification for the pricing contact.
&#61607;     If at least one of the pricing contact’s assigned contract and item combinations within the ZPRICE table has an entry date (ZPRICE.ERDAT) equal to today’s date trigger the output for this pricing contact.

hi,
dictionary interfaces: you define your interface with reference to dictionary objects (structures, ansd so on). If your form uses a dictionary interface you can use special types in your interface for texts (smartform or include texts), adresses, graphics, and so on...
if you use an XML interface and create it by your own you can upload a xml file that represents your data file.
XML Interfaces are created by the system if you create your form out of web dynpro abap (online scenario).
To use tables and information out of your application without web dynpro i would recommend you to use ddic interfaces, web dynpro xml.
