In DBC Finance, why is "New" disabled ?

In the File menu, New is disabled by default.

Just like in MS Word, New will create a new unnamed document (i.e. a Series).

But using New in DBC Finance tends to cause more problems than it solves.

This is because having multiple unnamed documents becomes confusing if you have to refer to them from other documents. And it becomes confusing later if you have to name the documents when you save them. Creating and naming the datafile and documents when you create them is preferable.

Datafiles

To access or create a datafile, hit the Open button on the Toolbar (or File | Open). The Open Datafile dialog appears.

Navigate to where the new or existing datafile should reside. Select from existing datafiles. To create a new datafile, indicate the name where prompted.

To access a datafile in the samples or tutorial folders distributed with DBC Finance, the user should copy them to another location.

Issuers

To create an issuer, you should have already opened a datafile (e.g. tutorial.df2).

Hit Open on the Toolbar. Click on Issuers in the tree. Hit New. Enter the Short Name and Long Name of the issuer. Hit OK.

Documents (Series, Case, Financing)

To create a document, you should have already opened a datafile (e.g. tutorial.df2).

Hit Open on the Toolbar. Click on issuer under which you want to create the document. Hit New. Specify the Document Type. Enter the Short Name and Long Name of the document. Hit OK. Note, Status and Component Gallery are beyond the scope of this document.
