1. An implementation project is where SAP is to be implemented and will involve a number of fresh ABAP developments.
A support project is where SAP is already implemented and ABAP work will be in the form of changes or bug fixing to the existing code and minimal new developments.
2.& 3. All companies will use some kind of Standards for their documentation and all their documents will be in a predefined template format. There will be templates available for Technical Specifications, Unit Testing documents, etc etc, that you use to fill in the requied details.
4. Most of the MNCs are CMM level-5 atleast and all these Capability Maturity Models (CMM) are based on one of the SDLC (Software development life cycle) - life waterfall model for ex.
5. SAP is 3 tier architecture which means there are thre layers - Presentation, Application adn Database.
Presenetations i teh GUI installed on your computer, application are the programs and the data tables that these programs access is the Database Layer.
An ABAP program is used to access database.
6. Yes BDC programs can be called in background mode.
7. A session is created by the BDC program.Go To SM35 transaction and execute the session.
8.Synchronous updates is updating real time, at the time of execution of your progra, Asyncronous updates are carried out whenever there is a database commit.
9. iN real time you use Call Transaction, because it triggers the transaction at the time of execution of the program. The main difference is taht in BDC session, you cal schedule the program to run at a particular time (say every night) and the errored records are held in a session. so you can correct the errors and run the session for errored records again.
Where as in Call Transaction, messages are held in an internal table it_msgcoll and you need to process that.
call transaction 'VL02N' using it_bdcdata
mode 'N'
messages into it_msgcoll.
10. SAP Scripts and Smart froms are client dependant. The rest- Reports, Module Pools, Function Modules, RFC, BAPI, IDOC are all client independant.
Standard texts are client independant.
11. IDOC Type is nothing but Basic type - Like MATMAS03is IDOC TYPE. MATMAS is MEssage Type. IDOC Type will define the IDOC Strcuture. Message tYpe will define the data classification - like Material, Sales Order, etc.
13. Cluster Table - BSEG, BSEC ,BSED
Pool - T008, T009 etc
Go to table contents of DD02L and enter the required TABCLASS- it will give you the list of tables.
Phew!!!! hope you reqard points for so much typing!
