I'm making an extension of the "Bank Account Ledger Entry" table, in which I need to create a new field called "Creation time", which would simply be the time that appears in the "SystemCreatedAt" field of type DateTime, already existing in the table. For this, I want to use the "DT2Time" function to extract the time part of that field and save it in the new field. The problem is, I don't know exactly where I should do this. Would it have to be done in a Trigger or something?
I know that the easiest thing is to do it directly in the page extension, but for this particular case, I need it to be a table field
