Re: What are Major differences in Smart forms and Scripts Answer

SAP Script is Client Dependent, Smartforms is Client Independent.

In Scripts We r unable print the Background Pictures but in Smart form can do.

In Scripts if u want to access any data from windows we must call the write_form for every window in Driver Program but in Smartforms when we are activating the smartform it automatically generates a FM, using the FM we can call all windows data From the smartform.

In Scripts Main window is mandatary but in smartform not necessary.

In Scripts if u want with work with Tables and Templates long process, in smartforms very easy to work using navigation.

Smartform is very user friendly than SAP Scripts.

data: itab1 type table of itab with header line.

Can any body explain me what is field group?

Field groups are groups similar fields together into one name. Field group works in conjuction with    

INSERT f1 f2 INTO fg
EXTRACT fg
SORT BY fg
LOOP ... ENDLOOP

INSERT f1 f2 INTO fg
---------------------

The insert statement is used to create a field group dynamically by inserting the field into it. Only global data fields can be inserted and not local data fields eg : in form modules.

EXTRACT fg
----------  

This will combine all the fields in the fieldgroup and write them to a sequential dataset as a single record.

SORT BY fg
----------

Sorting of sequential dataset by field group.

LOOP AND ENDLOOP

LOOP.
  AT ***
......
....

ENDLOOP.

STEP 3: 

DEPENDING UPON THE BDC TYPE 

i)call transaction(Write the program explicity) 

ii) create sessions (sessions are created and processed.if success data will transfer).

4. What is a batch input session? 


ANS:- 

BATCH INPUT SESSION is an intermediate step between internal table and database table. 

Data along with the action is stored in session ie data for screen fields, to which screen it is passed,program name behind it, and how next screen is processed.
