I have a simple buildtime design issue.

I have 4 activities in my model. Say the activities are A, B, C, and D. All 4 are UPES activities. My requirement is, activity D should to be executed 3 times, each after the execution of A, B, and C.

How do I design this?

I know I can achieve this by putting 3 program activities for activity D and by defining parallel connectors, like
1) A --> B and A-->D
2) B --> C and B-->D
3) C --> D.

I want to know, can we put only one prgram activity for D and still achieve this? If yes, how do we define the control connectors?

Put the UPES Activity "D" in a block and give the exit condion, say COUNT>4. Use this element in the Data structure using by BLOCK and increment this element it in your UPES Program, initiating with 0.

You can do it by putting all 4 activities in a block plus one more No Operation activity as the first activity of block.
No Operation activity will send flow to either A,B or C respectively in 3 iterations(Based on data connector value like a counter).
And these all are connected to D which is last activity of block.

So you model will something like this
1. No Op->A,No Op->B, No Op->C
2. A->D,B->D,C->D

Hope this is what you want to achieve...

Andy,
I got it what you said. I can work it out in your way.

mike_mg:
My requirement is D should be executed 3 times, each after the execution of A, B, C. With your solution, I think D executes 3 times continuously, but not parellally after the execution of A, B, C.

Anyway Thanks a lot for the responses.

Rajesh.
