Hi

Is It possible to remove field from a screen because useless ? Or maybe to rename It ?

It is possible with screen customization plugin

Hi i bought screen customization plug-in. is it normal that most of the field name cannot be updated (field is greyed in the plug in) ?

Moreover, is it possible to rename menu such as "ticket" for example?

Another question : i would like to put a default value on a reference field but it seems that it does not work. How to proceed ?

another question 🙂
How to make a list I created, depending on the existing product list ? I want to make a link between module & product

Again, where can i get the list of existing list of value to be able to add one in some screen?

No screen customiozation cannot manage menu names.
This is done by Personalized translation plugin, when you can replace any caption in any language.

Yes, you cannot rename existing fields.
You can just name and rename your new fields.

Another question : i would like to put a default value on a reference field but it seems that it does not work. How to proceed ?

Have a look at user manual of plugin.
Take care "default" value is managed only on creation.
It is not a calculated value, unless you set the field as readonly

You cannot.
Lists in the plugin are just lists of choice, they are not customisable objects.

On Parameter > List of values, you'll see all the existing lists of values.

I'm sorry but not a developper. Even when reading the user manual i do not catch what to do. How to set one value as default, for example the first one?

To define a fixed default value, just enter the value : "1" for instance.
To calculate the defaut value, use "###EVAL##xxxx" where xxx is some php code returning the expected value. But sure, you'll need a few ph knowledge to use this.

I'm sorry to say that if i put 1 or 2 for example, value by default is still the same (the figure is the ID of the item, you confirm?)

Please show your config and be sure to make changes on item.
I insist : defining default value will not automatically update exisitng items. This will be taken into account only for new items (or when updating item)

Hi
in fact, at ticket creation, the field is not visible (workflow rule). When the field becomes visible, the default value is not the one i "forced" in the customization plugin. Please clarify.

Default value won't work for hidden fields.
