8/2/2019 Days Count

How to get day counts between to given dates excluding Saturday and Sunday.?

Key for the given requirement is the date variable in ABAP itself. Actually date variable in ABAP is the count of

days from 01.01.0001 to given date internally.

So if we pass the date variable value to an integer variable and display it, it will display the day count for

01.01.0001 to the given date.

e.g: DATA: lv_date TYPE d VALUE '00010201',

lv_count TYPE i.

lv_count = lv_date.

WRITE:/ lv_count.

The output is 31.

Now to how to get the day of a date?

The answer again lies in the date variable. If we get the modulus of 7 for the date variable it 'll give the day as

2 -> Monday

3 -> Tuesday

4 -> Wednesday

5 -> Thursday

6 -> Friday

0 -> Saturday

1 -> Sunday

E.g. DATA: lv_date TYPE d VALUE '20120102',

lv_count TYPE i.

lv_count = lv_date MOD 7.

WRITE:/ lv_count.

The Output is 2 i.e 01.01.2012 is a Monday.

Now the following Function Module can be used for getting the day count excluding Saturday and Sunday.
