topic Data object recombination and process instances in Alfresco Archive https://connect.hyland.com/t5/alfresco-archive/data-object-recombination-and-process-instances/m-p/43290#M23557 <HTML><HEAD></HEAD><BODY><SPAN>Hi all,</SPAN><BR /><BR /><SPAN>in our logistics domain there is a typical process modeling pattern dealing with rearrangements in the flow of data objects (or business objects, BOs) between activities: data from different process instances is processed by one user task implementation and hereby merged to FEWER results, i.e. not every process instance gets a result. Hereafter the opposite occurs: data is recombined into a non-fixed higher number of results.</SPAN><BR /><BR /><SPAN>As an example, we have a coarse BPMN model A-&gt;B-&gt;C as shown below, where between these activities (e.g., a user task with complex internal BO rearrangement logic in its implementation, which may e.g. use a WMS (warehouse management system)) the following data objects flow:</SPAN><BR /><SPAN>- Each incoming BO-A message starts a process instance and leads to a BO-A-object as a result of activity A (this is simple). </SPAN><BR /><SPAN>- But in activity B several BO-A-objects (e.g. na=5, but varying, originating from different process instances) are combined into nb&lt;na BO-B-objects (e.g. 2, but varying). Only 2 process instances continue?</SPAN><BR /><SPAN>- Finally these objects are processed by activity C, resulting in nc&gt;nb BO-Cs (e.g. nc=4, but no fixed pattern). New process instances or threads are created?</SPAN><BR /><BR /><SPAN>Below is a variant of the model which uses only one process instance but data lists. Is the "Always receive messages of type BO-A" modelled right? </SPAN><BR /><SPAN>Another alternative would be to use data repositories between the tasks to enable the free recombination of objects. </SPAN><BR /><SPAN>How may such use cases be modeled and impemented best using BPMN 2.0 and especially Activiti (specifically, the control logic for the completion of such tasks)?</SPAN><BR /><BR /><SPAN>Thanks for any advice</SPAN><BR /><SPAN> Norbert Weissenberg</SPAN><BR /><BR /><SPAN>[attachment=0]BPMN-Problem.jpg[/attachment]</SPAN></BODY></HTML> Fri, 09 Dec 2011 11:29:34 GMT weissenberg 2011-12-09T11:29:34Z Data object recombination and process instances https://connect.hyland.com/t5/alfresco-archive/data-object-recombination-and-process-instances/m-p/43290#M23557 Hi all,in our logistics domain there is a typical process modeling pattern dealing with rearrangements in the flow of data objects (or business objects, BOs) between activities: data from different process instances is processed by one user task implementation and hereby merged to FEWER results, i.e Fri, 09 Dec 2011 11:29:34 GMT https://connect.hyland.com/t5/alfresco-archive/data-object-recombination-and-process-instances/m-p/43290#M23557 weissenberg 2011-12-09T11:29:34Z Re: Data object recombination and process instances https://connect.hyland.com/t5/alfresco-archive/data-object-recombination-and-process-instances/m-p/43291#M23558 <HTML><HEAD></HEAD><BODY><SPAN>Hi,</SPAN><BR /><BR /><SPAN>With Activiti data objects are typically implemented with Java, XML or JSON objects.</SPAN><BR /><SPAN>So you don't model them explicitly in your BPMN 2.0 process definition, but you can use the Activiti API to start a new process instance with a specific object and retrieve those objects during process execution.</SPAN><BR /><SPAN>So that's more flexible, but also less explicit.</SPAN><BR /><BR /><SPAN>Best regards,</SPAN></BODY></HTML> Fri, 09 Dec 2011 14:02:30 GMT https://connect.hyland.com/t5/alfresco-archive/data-object-recombination-and-process-instances/m-p/43291#M23558 trademak 2011-12-09T14:02:30Z
