Multi Select Lookup - Selected values in dynamic task expressions

Me and my colleague @Rune Andersland are trying to solve the exact same issue as you. Will let you know if we find a solution.

I was a long time ago given an expression crib sheet from Axios and it included this expression. (I have never used it and I have amended to your shortCode above)

if($new.W("MSL-BU").shortCode = "OPTION1", $NO_VALUE, 
if($new.W("MSL-BU").shortCode = "OPTION2", $NO_VALUE, $NO_VALUE))

The below is a working exaple of dynamic task expressions dependent on the value selected from a single-select lookup if that is of any use

if($new.W("BARCLAYS_AMEND ACCES PROFILE_ROLE DEFINITION").shortCode = "TREASURY SYSTEMS","TREASURY SYSTEMS",
if($new.W("BARCLAYS_AMEND ACCES PROFILE_ROLE DEFINITION").shortCode = "TREASURY","TREASURY",
if($new.W("BARCLAYS_AMEND ACCES PROFILE_ROLE DEFINITION").shortCode = "BACK OFFICE","BACK OFFICE",
if($new.W("BARCLAYS_AMEND ACCES PROFILE_ROLE DEFINITION").shortCode = "FINANCE","FINANCE",
if($new.W("BARCLAYS_AMEND ACCES PROFILE_ROLE DEFINITION").shortCode = "TAX","TAX",
if($new.W("BARCLAYS_AMEND ACCES PROFILE_ROLE DEFINITION").shortCode = "INSURANCE","INSURANCE",
if($new.W("BARCLAYS_AMEND ACCES PROFILE_ROLE DEFINITION").shortCode = "Z_OTHER","Z_OTHER",$NO_VALUE )))))))

Hi Kevin

The way I have handled this in the past is to 

1. Create a string field on the form that the other users cannot see
2. Add a “system” Stage and Task to the process before the stage where you want your dynamic task to trigger
3. Have associated with the creation of the above Task, a SmartMail job that will gather the values from the multi select values and format them in an array string that looks like as follows
   [“ASSYST”,”ASSYSTNET”,”ASSYSTWEB”,”ASSYSTDB”]
4. That Smartmail job has an update_event_ejb call that places that string in the aforementioned field you have created. Lets say that field short code is called SYSTEMS

    

   {"update_event_ejb",

      eventId = [[ PARENT_EVENT_ID ]],

    customFields =      [[

                                         {

                                             { customFieldShortCode = "SYSTEMS",

                                             stringValue = ""..ARRAY_STRING

                                             },

                                        }

                                   ]],

   },

5. It then closes the task moving onto the next stage for which the Dynamic Task expression reads $new.W(“SYSTEMS”).value 

6. Which for the above example string will produce 4 tasks for each element in that array, i.e. the systems chosen. 

If those values were valid item short codes then they can be substituted into the item A or B fields with the simple $DYNAMIC_TASK_VALUE expression returned for having a dynamic task expression
