FM / BAPI for cheching time collusion?

Former Member — Sat, 11 Sep 2010 16:51:06 GMT

Hello experts,

i´m looking for a function, that checks two date&time pairs for a collusion.

As example:

Pair 1 - Begin Date is 29.09.2010 time 10:00 End Date is 30.09.2010 time 22:00

Pair 2 - Begin Date is 30.09.2010 time 21:30 End Date is 01.10.2010 time 23:00

So the two pairs collide on 30.09.2010 at 21:30 for half an our.

Does anybody know a function which can handle this?

Thanks

Hi Benjamin,

Are you just wanting to check if there is a collision or do you need to determine how long there is a collision?

Hello Benjamin

I needed to do a FM to check this issue once.


FUNCTION zhrf030.
*"----------------------------------------------------------------------
*"*"Interface local:
*"  IMPORTING
*"     REFERENCE(I_REGEXIS) TYPE  ZHRST035
*"     REFERENCE(I_REGCRIA) TYPE  ZHRST035

  IF ( ( i_regcria-begda GT i_regexis-endda )                        OR
       ( i_regcria-endda LT i_regexis-begda )                        OR
       ( ( i_regcria-begda EQ i_regexis-endda ) AND
         ( i_regcria-beguz GE i_regexis-enduz   AND
         ( i_regexis-enduz IS NOT INITIAL AND i_regexis-enduz NE space )
                                                                  ) ) OR
         ( i_regcria-endda EQ i_regexis-begda ) AND
         ( i_regcria-enduz LE i_regexis-beguz   AND
         ( i_regcria-enduz IS NOT INITIAL AND i_regcria-enduz NE space
)
                                                                   ) ) .
    CLEAR vl_subrc.
  ENDIF.

* Verifica se o registro está OK
  IF vl_subrc IS NOT INITIAL.
    RAISE collision_found.
  ENDIF.
ENDFUNCTION.

Hope it helps

Hi Benjamin,

there is no standard functionm to handle this, but you could create one:

to have it more transparent in easier to understand, convert all Date/time pairs to timestamp:

DATA:
    lv_timestamp1  TYPE timestamp,
    lv_timestamp2  TYPE timestamp,
    lv_timestamp3  TYPE timestamp,
    lv_timestamp4  TYPE timestamp,
  CONVERT DATE iv_date1 TIME iv_time1 INTO TIME STAMP lv_timestamp1 TIME ZONE sy-zonlo.
  CONVERT DATE iv_date2 TIME iv_time2 INTO TIME STAMP lv_timestamp2 TIME ZONE sy-zonlo.
  CONVERT DATE iv_date3 TIME iv_time3 INTO TIME STAMP lv_timestamp3 TIME ZONE sy-zonlo.
  CONVERT DATE iv_date4 TIME iv_time4 INTO TIME STAMP lv_timestamp4 TIME ZONE sy-zonlo.
if lv_timestamp1 > lv_timestamp2 or
   lv_timestamp3 > lv_timestamp4.
* raise exception invalid date/time
endif.
  CALL FUNCTION 'IGN_TIMESTAMP_DIFFERENCE'
    EXPORTING
      i_timestamp1 = lv_timestamp2
      i_timestamp2 = lv_timestamp3
    IMPORTING
      E_DIFF_SECS = rv_n_of_seconds.
if rv_n_of_seconds < 0.
*  * raise exception date/time range collision
endif.

something like this.
