Use FM - HR_READ_INFOTYPE one time but to read mulitple Info types

Question

Dear All,
I have a select-option where in users enter the Info types Numbers.
Now I have to read and every infotype and display related data from each info type .
I have to use FM - HR_READ_INFOTYPE  but we need to declare data for each and every infotype so I need to use this 10 times in case If I have 10 infotype.
Is their any generlaised way exist where in I will pass the variable e.g., P0001 and build the internal table and use it for a FM. Kindly explain.
Regards,

Answer 1

Yes you can.
1.) Declare fields as follows:
FIELD-SYMBOLS <it> TYPE STANDARD TABLE.
DATA  l_table_name LIKE feld-name.
DATA: wa_0008 TYPE STANDARD TABLE OF p0008,
          0008_line LIKE LINE OF wa_0008.
2)  In Step 3 I have a form that you will need to call like this:
        MOVE 'wa_0008' TO l_table_name.
        ASSIGN (l_table_name) TO <it>.
        PERFORM read_infotype USING pernr
                                    '0008'
                                    begda
                                    endda.
        wa_0008 = <it>.
3) Your form will need to look like this
FORM read_infotype USING pers_num
                         it_num
                         begin
                         end.
  CALL FUNCTION 'HR_READ_INFOTYPE'
    EXPORTING
      pernr             = pers_num
      infty             = it_num
      begda             = begin
      endda             = end
    TABLES
      infty_tab         = <it>
    EXCEPTIONS
      infty_not_found = 1
      OTHERS          = 2.
  IF sy-subrc  = 1.
  ENDIF.
ENDFORM.                    " read_infotype
You can then call your form passing different infotype numbers to it.
Hope that helps.
