We have a template with several custome fields.

One of this custom field (Name of the field is "Horas") was generated as "Single Line" but we currently need that the field shall be a "Numeric" field.

We want to change the type from Single Line to Numeric Field and need that all the tickets with this field can be updated to "numeric" value in order to make some aritmetic functions with it.

However when we try to change the field attribute of "Horas" field all the options are grayed and no change is allowed.

I wonder if there is some way to perform this change and uptade the column table accordingly

Regards
