Can I control (make readonly/mandotory...) variables inside a multi row variable set

Can I control (make readonly/mandotory...) variables inside a multi row variable set with a catalog ui policy inside the item and not inside the variable set ?

Im trying to make a variable that in inside a MRVS read-only based on the value of a field that is on the item is this possible ? (Zurich Version)

Can you control MRVS variables with a catalog UI Policy on the item?

• No 😞 , not directly. In Zurich, UI Policies on the catalog item do not automatically apply to MRVS variables, because they live in a subform.

Workarounds:

1. Client Script on the catalog item

   • Use an onLoad/onChange script to loop through MRVS rows and set read-only/mandatory dynamically.

   g_form.getValue('item_field'); g_form.getSections('mrvs_name').forEach(function(row){ g_form.setReadOnly('mrvs_variable', true/false, row); });

2. UI Policy inside the MRVS

   • Use a hidden variable to pass conditions from the catalog item, then the MRVS UI Policy can act based on that.

At the End of the Day:

• Catalog-level UI Policies can’t directly control MRVS variables in Zurich.

• You need a client script on the item or a UI Policy inside the MRVS for dynamic behavior.

Hi @Matthew_13 so would something like this work ?

Also I want this to happen before the row is added, I want the "add_remove" to be "add" and "readonly" when the item variable value is "create", so that users can only use "add" when adding a new row.

(On the CI side)

if (newValue === 'create') {

	g_form.getSections('access_managment').forEach(function(row){ g_form.setValue('add_remove', 'add', row); });
	g_form.getSections('access_managment').forEach(function(row){ g_form.setReadOnly('add_remove', true, row);});

    }

Yes 🙂 , that approach should work!

You’re looping through each row in the access_managment MRVS and:

• Setting the add_remove variable value to 'add'

• Making the add_remove variable read-only

Just make sure:

• This runs at the right time (like onChange of the field controlling newValue)

• The variable and section names are spelled exactly as in your form

• You test it on multiple rows to confirm it applies everywhere

If you want, I can help you tidy it up or add a check to handle other newValue cases.

I must be doing something wrong, Im getting this error:

Error while running Client Script "Action = Create (Add/Remove)": TypeError: Cannot read properties of undefined (reading 'forEach')

I went to check if the internal name of the "MRVS" was right and it is 🤔
