Error #1547:
Cannot insert an empty row from a view into its base table(s)

Sources of this error:
1. Code: lnRetVal = REQUERY()
Method: requery
Object: arcustform1.pgfbizobj.page3.arcrefbizobj
2. Code: APPEND BLANK
Method: new
Object: arcustform1.pgfbizobj.page3.arcrefbizobj

Facts:

I created arcustform from cbizobjmaintenance form.
On Page 3, I added an object subclassed from clistobjedit. The bizobj in this page is arcrefbizobj. It is child table with view parameter vp_custno (from Page 1).

Cardinality is 1 to Many (arcustbizobj to arcrefbizobj)

I activated arcustform. On page 1, I selected the customer account (parent bizobj) and then clicked on page 3. I clicked Add pushbutton. I encountered intermittently this error (Source #2).

Another instance is to navigate from one customer account to another. I selected a customer in page 1 and then clicked page 3. I did not encountered any error. I repeated this several times, each time selecting different customer. I encounter this error (Source#1) intermitently.

Please be my mentor.
