Functions are evaluation procedures with which you can call up the value of a field or the results of a function module within aTemplate. A function is clearly identifiable through the environment, name space and logical function names.
Objects, quantities, activation requirements and assignment times are dynamically determined through the definitions ofMethods and Formulas for Templates. They are always assigned to environments or sub-environments (see Environment of the Template) , and can be structured or organized into function trees (see Function Trees).
You can use standard functions or define new ones (seeMaintaining Functions), this means that you can access exactly the right driver information that the respective enterprise needs. In addition to access to table fields and standard function modules, you can also create ABAP-function modules, whose results are accessible by the function (see Implementing ABAP-functions).
While creating functions, you determine, among other things, the following:
