I'm missing something because I fail to see what the problem is.

There is nothing special about the P_ prefix. You simply gave that as a name
for your parameter and told IBO the column in the master dataset to get its
value from. If you want that value to also be plugged into a column when
inserting a record you have to make the parameter name the same as the
column name to receive the value. That is the way I designed it to work and
that is what I believe it does. If it doesn't, that is what I will make it
do if you say it isn't doing that.
