Dialog WORK PROCESS: Deals with request to EXECUTE dialog steps triggered by an active user.
Update Work Process: Execute database update requests
Background Work Process: Execute the PROGRAMS that run without the involvement of the user
Enqueue Process: Handle the lock mechanism.
Spool Work Process: Passes sequential DATA flows on to printers

ACT as a bridge to connect DIFFERENT work processes with the respective users logged on to the SAP R/3 SYSTEM. The request received by the Application Server are first directed to the dispatcher, which enrolls them to a dispatcher queue. The dispatcher then retrieves the request from the queue on the first-in first-out basis, and allocate them to a FREE work PROCESS.

An update REQUEST can be divided into one PRIMARY (V1) and several SECONDARY update components (V2). Time-critical operations are placed in V1 component and those whose timing is LESS critical are placed in V2 components. If a V1 update fails, V2 components will not be processed.

Spool requests are generated during DIALOG or background processing and PLACED in the spool database with information about the printer and print format. The ACTUAL data is PLACES in the Term See (Temporary Sequential objects).

Macros can only be used in the program they are defined in and only after the definition are expanded at compilation / GENERATION. Subroutines (FORM) can be called from both the program they are defined in and other programs. A MACRO is more or less an abbreviation for some lines of code that are used more than once or twice. A FORM is a LOCAL subroutine (which can be called external). A FUNCTION is (more or less) a subroutine that is called external. SINCE debugging a MACRO is not really possible, prevent the USE of them (I’ve never used them, but seen them in action). If the subroutine is used only local (called INTERNAL) use a FORM. If the subroutine is called external (used by more than one program) use a FUNCTION.

CLIENT DEPENDENT or independent transfer REQUIREMENTS include client SPECIFIC or cross client objects in the change requests. Workbench objects like SUBSCRIPTS are client specific, some entries in customizing are client independent. If you display the object list for one change request, and then for each object the object attributes, you will find the flag client specific. If one object in the task list has this flag on, then that transport will be client dependent.

Disadvantages:

If you do not specify a LOGICAL database in the program attributes, the GET events never occur.
There is no ENDGET command, so the code block associated with an EVENT ends with the next event statement (such as ANOTHER GET or an END-OF-SELECTION).

BATCH input session is an INTERMEDIATE step between INTERNAL table and database table. Data along with the action is stored in session i.e data for screen FIELDS, to which screen it is PASSED, program name behind it, and how next screen is processed.

To read data from a database tables we USE logical database. A logical database provides read-only access to a GROUP of related tables to an ABAP/4 program. Advantages:

Check functions which check that USER input is complete, correct, and plausible.
 Meaningful data selection.
Central authorization checks for database accesses.
Good read access performance while retaining the HIERARCHICAL data view determined by the APPLICATION logic.

ALV is Application List viewer. Sap provides a set of ALV (ABAP LIST VIEWER) function modules which can be put into use to embellish the output of a report. This set of ALV functions is used to enhance the READABILITY and functionality of any report output. Cases arise in sap when the output of a report contains COLUMNS extending more than 255 characters in length. In such cases, this set of ALV functions can help choose selected columns and arrange the different columns from a report output and also save different variants for report DISPLAY. This is a very efficient tool for dynamically sorting and arranging the columns from a report output. The report output can CONTAIN up to 90 columns in the display with the wide array of display options.

Table contains vertical and HORIZONTAL lines. We can store the data in table as BLOCKS. We can scroll depends UPON your wish. And these all are STORED in database (data dictionary).

• ABAP/4 PROVIDES some interactive events on LISTS such as AT LINE-SELECTION (double click) or AT USER-COMMAND (pressing a button). You can use these events to move through LAYERS of information about INDIVIDUAL items in a list.
• Drill down report is nothing but interactive report...drilldown MEANS above paragraph only.

CALL transaction is faster then session method. But usually we use session method in real time...because we can transfer LARGE amount of DATA from internal table to database and if any errors in a session, then process will not COMPLETE until session get CORRECT.

We LOOK into the LIST of incorrect SESSION and process it again. To CORRECT incorrect session, we ANALYZE the session to determine which screen and value produced the error. For small errors in data we correct them interactively otherwise modify batch input program that has generated the session or many times even the data file.

We will LOOK into the error log file (SM35). Check number of records already UPDATED and delete them from input file and run BDC again.
