Hi, question regarding custom fields that are sourced onto transaction records. I need to 1) put a field on an invoice that say for this example sources the address of the related subsidiary. 2) once that address is sourced , I would like that field to stay the same - meaning if I changed that related subsidiary address later, the subsidiary address custom field I created on the invoice - would remain as it was - meaning I want to initially source the information and afterwards make the information permanent on that record
