PB classic to PB.NET migration: Protect property expression missing after migration

Hi,

In pb classic, for the Protect proterty of one column in a dwo, we have the following expression and that works fine -

if(isRowModified()  and   ( column_x =   column_x.original or isnull( column_x)) or  column_y = 'T',0,1)

After migration to PB.NET, we found that the Protect property expression was not migrated. When we manually try to put the same expression in PB.NET Protect property, we get the message Expression Not Valid.

Any idea why so with PB.NET ? Is it use of columnname.original which is invalid in PB.NET and thats' why not getting migrated? What should be done to overcome the issue ?

We are using PB version 12.5.2 build 5583.
