Please post DDL, so that people do not have to guess what the keys,
constraints, Declarative Referential Integrity, data types, etc. in
your schema are. Sample data is also a good idea, along with clear
specifications. It is very hard to debug code when you do not let us
see it.

But the code implies some design problems. What are the logical
differences among
PositionsPZZW, PositionsWZRW and PositionsMM ? This looks like
attribute splitting.

Why are you using triggers instead of DRI actions?
