scope:

This specification provides the definition of the Quantity Valuation message (CONQVA) to be used in Electronic Data Interchange (EDI) between partners involved in Administration, Commerce and Transport. Typically this message will be used for a contractor to submit progress details to a client or his representative. The message will be used also for subsets of the project where work has been contracted out to other parties. In these cases the exchange would be between the subcontractor and the party that subcontracted the work.
