*set up variables

data: endmessage(100),TEXT2(20) type c.

data: lv_string(250) type c.

data: fname(60).

data: TEXT1 type string.

  DATA: ld_day TYPE c.

* Call function to get the day number using the system date sy-datum

  CALL FUNCTION 'DATE_COMPUTE_DAY'

       EXPORTING

            date = sy-datum

       IMPORTING

            day  = ld_day.

* Depending on the value returned to ld_day which will be a value from 1 to 7 - create a name for the output file which is different each day.

* Now create the variable part of the %SELECTION% parameter which will pick differing values of the category dimension depending on what month number is in the system date sy-datum 2 characters starting from position 4

*Note the values created by BPC for the %SELECTION% prompt are preceded by

*Now join the parts together and make sure that you insert a horizontal_tab between the parameter name and its value and also put a CR_LF at the end of each line.

Concatenate:'%SELECTION%' cl_abap_char_utilities=>horizontal_tab TEXT1 CL_ABAP_CHAR_UTILITIES=>CR_LF '%OUTPUTFILE%' cl_abap_char_utilities=>horizontal_tab TEXT2 CL_ABAP_CHAR_UTILITIES=>CR_LF INTO lv_string.

fname = '/usr/sap/trans/BPC_PROMPT.txt'.

OPEN DATASET fname FOR OUTPUT IN TEXT MODE encoding default.

transfer lv_string to fname.

close dataset fname.

Concatenate:fname '  created sucessfully backup file will be called  -   ' TEXT2 into endmessage.

write endmessage.
