The date variable in ABAP/4 have format "YYYYMMDD". If you want to get no. of year, month or day for the date, you can offset this variable.

Example

DATA: lv_date TYPE D VALUE sy-datum,    "20050312
      lv_year(4),
      lv_month(2),
      lv_day(2).

lv_year = lv_date(4).       "2005
lv_month = lv_date+4(2).    "03
lv_day = lv_date+6(2).      "12 

If you want to find next n day of the date, you can apply opration sign ’+’ to this point.

Example

We can apply function module "CONVERSION_EXIT_ALPHA_OUTPUT’ to convert string number to integer without leading zeroes.

Example

  DATA: lv_number TYPE I,
        lv_string(10) TYPE C VALUE ’0000000012’.
  
  CALL FUNCTION ’CONVERSION_EXIT_ALPHA_OUTPUT’
    EXPORTING
      INPUT         = lv_string
    IMPORTING
      OUTPUT        = lv_number
            .

  

We can apply function module "CONVERSION_EXIT_ALPHA_INPUT’ to convert number into string with leading zeroes.

Example

  DATA: lv_number TYPE I VALUE 12,
        lv_string(10) TYPE C.
  
  CALL FUNCTION ’CONVERSION_EXIT_ALPHA_INPUT’
    EXPORTING
      INPUT         = lv_number
    IMPORTING
      OUTPUT        = lv_string
            .

  

Normally, when you want to read the file from application server, you will have 5 steps:

1. Open file in application server by statement:
   

   OPEN DATASET file_name FOR INPUT IN TEXT MODE.

2. Checking the file is opened sucessfully by SY-SUBRC = 0
3. After checking, you can read data from file by statement:
   

   READ DATASET file_name INTO itab.  
   Note: This statement should be in DO statement

4. Append data to internal table
5. Close file by statement:
   

   CLOSE DATASET file_name

Example

Normally, when you want to transfer data the file to application server, you will
have 3 steps:

1. Open file in application server by statement:
   

   OPEN DATASET file_name FOR OUTPUT IN TEXT MODE.

2. Transfer data from file by statement:

   TRANSFER itab TO file_name. 
   Note: This statement should be in LOOP statement for Internal table

3. Close file by statement:

CLOSE DATASET file_name.
