In addition to this case:
have we now implemented an update in which you can rollforward a file from one database variable to another (previously, that was only possible to the same variable).
Easy code example:
{% input custom.invoice.pdf_1 as:file %}
{% input custom.invoices.last_year as:file %}
{% comment %}
ROLL FORWARD logic
{% endcomment %}
{% rollforward nil custom.invoice.pdf_1 as:file %}
{% rollforward custom.invoice.pdf_1 custom.invoices.last_year as:file %}
As you can see, I will set the original database variable to nil, and roll forward it to another db variable.
Please do not mind the naming of the database variables; it’s an example to clarify the new coding
