How do I create a button on a form that will save the current record, copy some of the fields to a new record, and redisplay the new record in edit mode?

There are two ways to go here. Low Tech and high Tech.

Low Tech

You will notice that when you use the More button while viewing a record and click to Copy this Record, the URL you see looks like this


mycompany.quickbase.com/db/xxxxxx?a=GenCopyRecord&rid=770

So the low tech solution is just to make a URL formula button to make that URL

The formula would be

URLroot() & "db/" & dbid() &  "?a=GenCopyRecord&rid=" & ToText([Record ID#])

When you use that option by default all the data entry fields on the form will copy across to an Add Record Form.  If you do not want certain fields to Copy across then you individually go to each field that you do not want to copy across and uncheck the property

Auto-fill Copy the value when using "Copy this Purchase Order" to add a new Purchase Order

The best way to quickly get to the field Properties is to right click near the field on the form.

The only downside of this method is that if any fields on the form are set to be Read Only or are not visible on the form, I don't think that they will copy across.

Higher tech

So the more reliable way would be to use an API

Here is an example

URLRoot() & "db/" & Dbid() & "?act=API_GenAddRecordForm"
& "&_fid_12=" & [Purchase Order #]
& "&_fid_42=" & URLEncode([Component or Bulk item?])
& "&_fid_38=" & [Related Bulk item Master]
& "&_fid_24=" & [Related Component]
& "&_fid_28=" & ToText([Line Item Cost Override])
& "&_fid_53=" & URLEncode([PO Line Comment])

Note that when you use this method you are building a URL, and URLs may not have spaces or specials characters in them.  So where there might be a strong that you are putting into a field, which might have special characters or spaces you need to URLEncode as I have done above.  The "fid's" are the field ID numbers.

Lastly, if you did decide that you wanted to actually create the record and display it to the user, then you could do this

URLRoot() & "db/" & Dbid() & "?act=API_AddRecord"
& "&_fid_12=" & [Purchase Order #]
& "&_fid_42=" & URLEncode([Component or Bulk item?])
& "&_fid_38=" & [Related Bulk item Master]
& "&_fid_24=" & [Related Component]
& "&_fid_28=" & ToText([Line Item Cost Override])
& "&_fid_53=" & URLEncode([PO Line Comment])
& "&disprec=1"
