Urgent ! Exit code to calculate End Date (31/12/9999) to Current system Dat

Question

Dear All,
I have a scenario where i need to calculate Position time hold by an employee in an organisation.
I have 2 date Char ( DATE FROM & DATE TO), the problem is that is , If an employee is having
2/3 position in an organisation its current position End Date is always 31.12.999 as its End date is
not know. For previous position End Date is maintained.
My requirement is to calculate Position hold time including Current position.
I have created 2 Formula Variable on Date From & Date To,
The issue is that Date To is having both Values Previous Position Date thats ok as its not 31/12/9999
I am geting those values in Forumla in addition its also having Date For Current position as 31/12/9999
which should be converdet in to current system date.
I need to write a User Exit on End Date Forumla Variable which should only convert if Date = 31/12/9999
else leave it as it.
For EX,
EndDate
1/1/2005
1/1/2006
31/12/9999(Only this value need to convert as current system date and leave above valuse as it)
Can any one please provide me the code for this, this is v urgent.
Thanks V V much.
Regards,

Hi Dilek,
I now understand what you were writing.
I played around a bit and it still doesn't work like I want to.
The really strange thing is when I adapt an existing (SAP - standard) dynamic action (for another IT)  the 'calculation part' is performed and with my own attempt it doesn't substract the day.
0442              BEGDA     06     10     P     T001P-MOLGA='05'
0442              BEGDA     06     20     I     MOD,0014,1539
0442              BEGDA     06     30     W     P0014-ENDDA=P0442-BEGDA
0442              BEGDA     06     50     W     P0014-VTROP='-'
0442              BEGDA     06     55     W     P0014-VTRAN='1'
0442              BEGDA     06     60     W     P0014-VTRZH='010'
If IT0442 is created or changed, IT0014 with subtype/wagetype 1539 should be delimited with enddate = (startdate IT0442 -/- 1 day)
If you can have a look whether I mak e an obvious mistake, it's appreciated.
In the meantime I'll fiddle around as well at my end.....
Thanks,
Wilfred.
