Date and Time calculation in the Service Module

Question

Dear all,
I have quite of a challenge here and i need serious guidance from your side.
My client is in services industry and requires to calculate the date and time when the service call as to be closed. Not only it depends on the contract type the service is linked to but as well on the priority.
The priority in Business One is unique, therefore we created a UDT (User Defined Table) to store the different 'response time' per contract/per priority. Example: a Platinum contract is always 24/7. But a gold contract priority 1 has to be closed in 240 minutes (4 workable hours) while a gold contract priority 2 has to be closed in 480 minutes (8 workable hours).
I created 7 user defined fields on the Service Contract header that calculates the workable minutes per day. So if my coverage for Monday is from 8 AM to 4 PM, my UDF called DiffMon will show 480. For Tuesday, they start a bit later, and the coverage is 8:30 untill 16:00, therefore my UDF called DiffTue = 450.If the check box before the day in the Service Contract window is not ticked, then the UDF shows zero.
I succeeded to calculate the expected closing time by using CASE WHEN statements as following, (all calculated in minutes):
     First, I need to check which day the Service call is created: A Monday or Thursday or... since my time coverage can change every day! I use SET DATEFIRST = 1 and compare today's date accordingly with my UDF DiffMon, DiffTue, etc.
     Then, When end of coverage time today Monday (4PM) minus the create time on the Service Call (1PM) is less then the time stored in my user defined table for that contract and that priority (i.e.480), then just add that to the create time and the create date (DateAdd(mi,...,...) ).
    When end of coverage time Monday (4PM) - Create time (1PM) + DiffTue(450) is bigger than 480, then I know I have enough time to solve my service call tomorrow Tuesday and I take the start time of Tuesday (8:30) + remaining time from yesterday (480-180 -> 180 = 3hours from 1PM to 4PM) and add that to the Create date + 1 so the end result will show Tuesday date and a time of 13:30
   Etc. untill I cover all possibilities based on which day is the service call created.
NOW, I need to include the holiday table !!!!!!!!!!  And I can't foresee how the hell I am going to do that.
The maximum coverage can go up to 60 hours, that means more than a working week! What happens if I have more than one bank holiday in that week period? What happens when my holiday table tells me that  date is a bank holiday but it is actually a Sunday and my contract is only running from Monday to Friday?
Am I going straight to a big mess up?
I will highly appreciate your comments,
Regards,
Frederic

Hi,
it is possible in query designer,
u do the two things for getting the days between to dates
1) in CMOD write the code for sy-datum create a customer exit variable in query as on caldate like eg zcedate
when 'zcedate'.
clear l_s_range.
l_s_range-sign = 'i'.
l_s_range-opt = 'eq'.
l_s_range-low = sy-datum.
append l_s_range to e_t_range.
u write this code exit_saplrrso_001.
it givs the sydatum
2) then u create one more variable on zdate limit with replacement path
then u go forto create the formula variable then it display ascreen there u select both customer exit variable and replacement path variable
zcedate-replacementpathvariable
it gives days i worked on this and succedded.
like the same way fortime also u can do but here at the time of creating the customer exit varible u go for option as range here
l_s_range-low = '20012009'
l_s_range-high = '29012009'
l_s_range-sign ='i'.
l_s_range-opt = 'bt'.
please try with the above one.
Thanks & rEgards,
