Processing a search case operation result

A search case operation result is often used with an update case operation. Since an array is returned in a search case result, you would use JavaScript to iterate through each element of the array and perform multiple updates.

Follow these steps to make multiple updates using a search case result.

Although this topic is about a search case, it could also be applied to a retrieve case.

For example, you could search for a case and for each case reference returned perform a retrieve to get the properties of each case instance. You could look upon this example as a pattern that can be used any time multiple case references need to be processed.

Procedure

1. In the IBM Case Manager Integration Service editor, create a flow of operations similar to the following screen capture.

   

2. In the Loop Case References component, add JavaScript similar to the following in the Implementation section of the Properties view. It will let the loop run until there are no more cases in the array to process.

   /* Assumes that the counter variable will always be reset to -1 at the end of the loop */
   tw.local.counter ++; /* Increase the counter by one */
   tw.local.currentReference = null; /* Reset the current reference */
   
   /* If the counter is within the length of the array, get the next case reference */
   if(tw.local.counter <= tw.local.references.listLength){
       tw.local.currentReference = tw.local.references[tw.local.counter];}else{
       /* Else, reset the counter.  The Reference is 
          already null so the decision node should continue */
       tw.local.counter = -1;
       }

3. In the Implementation section of the Properties view for the Decision Gateway, return the flow to the Update Case service when the currentReference variable from the JavaScript shown previously is not equal to a null value.

4. Create a query to run against your IBM Case Manager solution as shown in Building a query for a search case operation.

5. Run the business process that invokes this service.

   A different situation to the one described in the previous steps is if you update a case instance in IBM Process Center that originated on the IBM Case Manager server. When you return that case instance to the IBM Case Manager server, use the tw.system.enclosingCaseInstance system variable as the reference to the case instance running on the IBM Case Manager server. This variable is only available at the business process definition level.
