How to add certain value to a marketplace field according to the form in which it is used?

The following dynamic expression is useful when we have a field shared between several forms and we would like the field to take a value depending on the form.

Copy this code:

fil.doctype.name == 'doctype_name_1' and 'valor_1' or fil.doctype.name == 'doctype_name_2' and 'valor_2' or 'valor_por_defecto'

Got to  Config metadata extraction in the field menu.

Paste de expression in Dynamicexpression. Then you need to replace the names of the forms and the values for each form.
