It has to do with maintaining referential integrity. The detail record
cannot exist in the database unless there is a master record already
present. Typically this was dealt with using cached updates and being sure
to resolve master datasets prior to the detail. This way, you get to avoid
using cached updates.

Great

This is exactly what I needed.

Thanks Jason!

Just out of interest, was I correct in my understanding of why there
is a PostRetaining after the first Detail record is posted?
That the Master needs to confirm that it itself can be posted first?
