Want to get request number to BPEL process in an interval

Question

Hi All,
I have two applications A and B.I need to receive request message from A to B through BPEL process. BPEL process receives the request data(through schema- Source of transform activity) from A and updates that data into B(Target -request schema of B).BPEL process is the middleware between two applications
My requirement is :
I want to analize request data in an interval of 24 hours. I have one parameter('sequence') in the request schema of B which has to indicate the request number to BPEL process.
Clear explanation to requirement details:
Application A starts pushing data at 12 'o clock(0:00 hrs midnight) and then parameter 'sequence' should be integer 1 or 0.Like that 'Sequence' should be increased by 1 for every request to BPEL process.
I want the sequence values like below(for 24 hrs cycle):
First request :
Reuqest push time - 0:00 hrs
Sequence - 1
BPEL process instance(which will be created automaically in EM console) - Instance1
Second Request :
Reuqest push time - 1:30 hrs
Sequence - 2
BPEL process instance(which will be created automaically in EM console) - Instance2
1
Third Request:
Reuqest push time - 4:00 hrs
Sequence - 3
BPEL process instance(which will be created automaically in EM console) - Instance3
Like that
last request in 24 hrs cycle should be :
Reuqest push time - 23:00 hrs
Sequence - Some number according to number of requests at that time.
After 24 hrs ,Sequence again should become as 1 to indicate the starting point of the 24 hrs next day.(like data in above table)
Can you help me in this regard? I am using transform activity in which I have 'sequence' parameter .
Thanks in advance

Answer 1

Create a "While" activity.
Create a variable named seq of type int.
In the while condition check the current time.
xp20:current-time() < <counter reset time>
Create a pick activity to receive the message inside while loop.
Create assign activity in the while loop. Assign the value of variable seq to the payload and increment it by one.
Outside while loop , reset seq back to 0 by using another assign activity.
In case the composite has to run continuously after first submission, use another outer while loop to check the condition while seq = 0.
Hope it helps.
Regards.
