Date Arithmetic

[Landry, Marcel]

Alon,  we have an object "ZDATE" which has one method to calculate a =
future
date based on two parameters, Date & Duration. NewDate =3D (Date + =
Duration).
 
This object also has two attributes that calculate (Date-1day) and
(Date+1day) for 'quick' values without having to call a method/task in =
the
workflow.   Once the reference date is obtained, it is passed to the
Workflow Container ZDATE and then the attributes can be interrogated.
 
 
Marcel.

Hi Guys,
 
Am I doing something wrong or is there no way to add a day to a date
container
element using a container operation?
 
For Example, If i have a container element which is declared as =
syst-datum
and
i want to add 1 day to it. If i try to do this in a container operation =
it
tells me that '1' is not a valid date format. Do I really have to =
create a
method to do this?
 
Regards,
 
Alon Raskin
