Field &1 cannot be used in the template

What causes this issue?

You cannot use the &V1& field in the template.
You created a scenario that incurs costs. To calculate the exact costs
of this scenario, you need to specify a template.
The template can only work with characteristics that have a field
length of <ZH>up to</> 30 characters.
The &V1& field has a length of &V2& in the dictionary. Therefore it
would be offered in neither the quantity editor nor the activation
editor template.

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

If you want to make the scenario costing dependent on the content of
the &V1& field, choose a dictionary category that has a field length of
<ZH>up to<I> 30 characters.
