Hi Henri, I might be wrong but there's no straightforward way to easily accomplish this. I'm not saying, it is not possible, but it'll require some tricks to get there.

There are also some details we're missing to give you the full solution, but either way here's an idea of how you could get it to work (and possibly tweak it where necessary).

In my proposal, I'm making use of the following: Configuring a page to update a session variable when another session variable changes | DataMiner Docs. With this functionality, you can set a session variable with dynamic content. Whenever the dynamic content changes, the variable gets updated.

Example: Make a new Shape Data field on the page level:

• Execute: Set|Variable|TempVar|[var:myVar]|SetTrigger=ValueChanged

Whenever the session variable 'myVar' changes, it will be filled into the session variable 'TempVar', i.e. TempVarwill be a copy of myVar.

Now you only want to change another variable whenever myVar is equal to something, i.e. you only want to trigger the above statement in certain cases. Possibly you also don't want any of the content of the value of 'myVar' in the content of the resulting session variable. To overcome this, you'll need to make use of the following placeholder: [RegexReplace:x,y,z].

Again, not all details of how you see this are in the question, but let's assume the following: 'if 'myVar' changes to 'value1' then (and only then) I want to trigger a change. You could see this as an 'if-statement' which you can implement by using two times the regexreplace placeholder:

Set|Variable|TempVar|[RegexReplace:[var:myVar],[RegexReplace:^value1$,[var:myVar],myValue1Changed],[var:TempVar]]|SetTrigger=ValueChanged

If myVar now changes to 'value1', TempVar will have the value 'myValue1Changed', otherwise, it will keep its value. The same applies to doing it for another value, e.g. 'value4' in my conclusion below.

Now the last step is to set the output session variable 'ResultVar1'. The same format is applied and is again an 'if-statement'. If TempVar changes to 'myValue1Changed', it will set the variable 'ResultVar1' with 'newvalue1.1' and otherwise keep its content. The same again applies to the other session variable.

Set|Variable|ResultVar1|[RegexReplace:[var:TempVar],[RegexReplace:^myValue1Changed$,[var:TempVar],newvalue1.1],[var:ResultVar1]]|SetTrigger=ValueChanged

In the end, you will have the following shape data on the page level:

• Execute: Set|Variable|TempVar|[RegexReplace:[var:myVar],[RegexReplace:^value1$,[var:myVar],myValue1Changed],[var:TempVar]]|SetTrigger=ValueChanged-Set|Variable|TempVar|[RegexReplace:[var:myVar],[RegexReplace:^value4$,[var:myVar],myValue4Changed],[var:TempVar]]|SetTrigger=ValueChanged-Set|Variable|ResultVar1|[RegexReplace:[var:TempVar],[RegexReplace:^myValue1Changed$,[var:TempVar],newvalue1.1],[var:ResultVar1]]|SetTrigger=ValueChanged-Set|Variable|ResultVar1|[RegexReplace:[var:TempVar],[RegexReplace:^myValue4Changed$,[var:TempVar],newvalue4.1],[var:ResultVar1]]|SetTrigger=ValueChanged

Of course, there could be other options, e.g. doing the logic through Automation or a connector, but here's a Visio-only solution presented. If you want now to add more ResultVar's then it's a matter of copy/paste.

Kind Regards,
Jarno
