Hi,
are there any possibilities to count how often a workitem has started (looped) without using an external program or service? That means can I define a member of a data structure in way like: DataStructure.Member=DataStructure.Member + 1
Thanks in forward |

| Ya. You can add one more element to the data structure and add the logic. |

This is not possible, you need to increment the member inside some activity. The Java Snippet from WPS would ge great here 
I am not sure what you are trying to do here, so this may not help, but you can also use the data in the Audit Table to know how many times a particular workitem looped.

A short description of the problem:
I have a workitem in which a customer will get a reminder to send in some papers. He will get maximal 3 reminders. After that third reminder the process should stop. With just 3 loops it is easy to define this behavior in the logic of the model but how should I do it when it is allowed to loop 40,50 or 100 times.
To do the calculation in a service isn't complicated as well. But in cases like this I always get a question from the HOST or Java programmers why MQWF isn't able to do a simple calculation like 1+1. (I'm just responsible for business logic and workflow modelling, not for UPES or anything else)
Until today I was always pretty sure that MQWF can't calculate. But after so many questions I'm afflicted by doubts. |

Kelme:
You are 100% correct, WMQWF can not do the calculation directly on the data connector as it appears your questioners would like.
A simple solution to this issue has always been the same. Define a member i, initialize it to 0, prior to entry into the block you are looping through. Within the block increment i. Specify the Block Exit condition based on i and how many times you wish to loop.
Note that in my example I am using Block, but this could be a single activity looping via it's exit condition also.
