WD4A - How to Calculate next 12 months from current month in web dynpro ABAP

Scenario- based on current date and month, user wants to select any month from the next 12 months. So as a developer you want to display in a list the next 12 months. For this you need to calculate next 12 months from the current date. Below written code does this and stores the next 12 months in a internal table. Later this internal table is bound with a context node to display next 12 months in a table or in a list (as user wishes) on the screen.

Technology used - Web Dynpro ABAP.
Programming language - ABAP.
Aim - calculate and store next 12 months from the current month in a internal table.

code is given below.

  types : BEGIN OF ty_to_date,
  name(20) type c,
  value(20) type c,
  END OF ty_to_date.
data : it_to_date type table of ty_to_date,
      wa_to_date type ty_to_date.

 data : date(12) type c.

data: year(4) type c,
      month(2) type c,
      day(2) type c.



data: imonths like sy-datum.

move sy-datum to imonths.



do 12 times.
  imonths+4(2) = imonths+4(2) + 1.
  imonths+6(2) = '01'.
  if imonths+4(2) = 13.
    imonths+4(2) = '01'.
    imonths(4) = imonths(4) + 1.
  endif.

  year = imonths(4).
month = imonths+4(2).
day = imonths+6(2).
CONCATENATE month '.' year INTO date.
  wa_to_date-name  = date.
  wa_to_date-value  = date.
  append wa_to_date to it_to_date.
enddo.


Bind the internal table to a Context Node to display list of next 12 months in a table or somwehere on the web dynpro ABAP Application screen.
  target_node->Bind_Table( it_to_date ).

Target node has the same structure as the structure of the ty_to_date created above.
