Customizations lost on Sales Invoice

I used to have customization in my sales invoices which included the Wire Transfer Details for companies wishing to make payments. I suddenly cannot find them anymore in new invoices generated. Also - I had a special numbering system where the prefix “FST-INV-” Used to precede the invoice number. I cannot find it any more. Whats going on guys?

You will need to be more specific, @thauseef.

Where did the wire transfer details appear? As business details? In notes? As part of a custom view template?[quote=“thauseef, post:1, topic:6607”]

This feature was part of a Settings category named Sales Invoice Template. That category was eliminated long ago.

I suspect you must have updated from quite an old version of Manager.
