Set up filtering by GCN set

A GCN set consists of a collection of gas contracts. The GCN Summary window allows controllers to filter the displayed information by GCN set.

Adding a new gascontract record to a GCN set is a one- or two-step process, as follows:

1. Either create a new gcnset record (see Create a GCN set), or, if you want to join a new gascontract record to an existing gcnset record, perform Step 2 only.

2. Join a new gascontract record to a gcnset record by means of the GCN Set Join (gcnsetjoin) table (see Add a gas contract to a GCN set).
