Invisible recurring section in sale invoice

[Fernando_Sanchez1]

I can not see the “recurrent” section in sales invoices. For what is this? I need to install or update something?
Thanks in advance.

@Fernando_Sanchez1, Recurring Invoice section will appears after saving the Sales Invoice form.

Subscription feature is disabled? What is the relation with recurring invoice?
