ABAP Programming Types
In SAP,each ABAP Program has the Type ,based on the Program Type ,we can understand what is that kind of program.There are 8 programming Types .
When a program is created, the suitable statement is automatically generated by the ABAP Workbench and should be changed during editing in the additions only. In particular, the keywords FUNCTION-POOL, CLASS-POOL, INTERFACE-POOL, and TYPE-POOL should be created solely by the respective tools of the ABAP Workbench and never be entered in the source text themselves in order to avoid unexpected system behavior.

I BAPIs are standardized programming interfaces (methods) enabling external applications to access business processes and data in the R/3 System. BAPIs provide stable and standardized methods to achieve seamless integration between the R/3 System and external applications, legacy systems and add-ons. BAPIs are defined in the BOR(Business object repository) as methods of SAP business object types that carry out specific business functions. BAPIs are carried out as RFC-enabled characteristic modules and are created within the Function Builder of the ABAP Workbench.
