Date Format IN BDC

Question

Hi,
In One Interview I was asked that How can You Handle Data Format when Writing BDC ?

Answer 1

Satya,
The date format depends on User settings. Its different for different login ID's.
It can be YYYY.MM.DD or MM.DD.YYYY or anything.
To handle the date format, you need to query on table USR01 and fetch DATFM field that stores date format.
Refer below piece of code
*/...Fetch the date format settings for the user
      SELECT SINGLE datfm
               INTO gv_date_format
               FROM usr01
              WHERE bname = sy-uname.
  CASE gv_date_format.
    WHEN 1.     "DD.MM.YYYY
      CONCATENATE fv_impdate+6(2) '.'
                  fv_impdate+4(2) '.'
                  fv_impdate+0(4) INTO fv_expdate.
    WHEN 2.     "MM/DD/YYYY
      CONCATENATE fv_impdate+4(2) '/'
                  fv_impdate+6(2) '/'
                  fv_impdate+0(4) INTO fv_expdate.
    WHEN 3.     "MM-DD-YYYY
      CONCATENATE fv_impdate+4(2) '-'
                  fv_impdate+6(2) '-'
                  fv_impdate+0(4) INTO fv_expdate.
    WHEN 4.     "YYYY.MM.DD
      CONCATENATE fv_impdate+0(4) '.'
                  fv_impdate+4(2) '.'
                  fv_impdate+6(2) INTO fv_expdate.
    WHEN 5.     "YYYY/MM/DD
      CONCATENATE fv_impdate+0(4) '/'
                  fv_impdate+4(2) '/'
                  fv_impdate+6(2) INTO fv_expdate.
    WHEN 6.     "YYYY-MM-DD
      CONCATENATE fv_impdate+0(4) '-'
                  fv_impdate+4(2) '-'
                  fv_impdate+6(2) INTO fv_expdate.
  ENDCASE.
This would convert the date into the format set for user.
Hope this is helpful.
