# Calculate Date/Time Interval

320 Views

I would like to know how to calculate a Date/Time Intervall.

There will be two selection options. In the first one you can enter a range of date. In the other one have the ability to enter the corresponding time.

Now i need an algorithm which calculates the timinvervall.

I have variables with date and time as timestamp and also separatet as date and time.

Now I would like to list the dates in an alv grid.

An Example:

Selection dates:

Date: 08.03.2013 to 08.03.2013

Time: 09:00 to 12:00

The format of the output I am expecting:

09:00 10:00

10:00 - 11:00

11:00 - 12:00

The Intervall is exact one Hour.

Does anyone know how to code this in abap?

Coding:

*********************************************************************
" Selektion screen
SELECTION-SCREEN FUNCTION KEY 1.

SELECTION-SCREEN BEGIN OF BLOCK a100 WITH FRAME TITLE text-100.
PARAMETERS p_lgtyp LIKE z9labpo-lgtyp DEFAULT 'ATL'.

SELECT-OPTIONS s_datum FOR z9labpo-datum.
SELECT-OPTIONS s_zeit FOR sy-uzeit.
SELECTION-SCREEN END OF BLOCK a100.
**********************************************************************

lv_datum_low = s_datum-low.
lv_zeit_low = s_zeit-low.

CALL FUNCTION 'DATE_CHECK_PLAUSIBILITY'

"convert to timestamp

CONCATENATE lv_jahr lv_monat lv_tag INTO lv_datum_low.

SPLIT lv_datum_high AT '.' INTO lv_tag lv_monat lv_jahr.
