Hi Jeremy,

You can't really override an ECA definition but you could override the service 
"createAcctgTransForShipmentReceipt" and place the additional condition in a 
new implementation.
So basically you would:
1. Define a new service called createAcctgTransForShipmentReceipt that points 
to a new custom implementation
2. Define a service that points to the existing implementation, maybe 
ofbizCreateAcctgTransForShipmentReceipt
3. Include your condition in the new implementation for #1, if it passes then 
call #2

Regards
Scott
