=head1 DESCRIPTION

=item new PARAMS

Constructor for CSV-DATEV export.

Checks mandantory params as described in section synopsis.

Furthermore C<params{locked}> is a perlish boolean.

=item _csv_buchungsexport

Generates the CSV-Format data for the CSV DATEV export and returns

an 2-dimensional array as an array_ref.

May additionally return a second array_ref with warnings.

Requires the same date fields as the constructor for a valid DATEV header.

Furthermore we assume that the first day of the fiscal year is

the first of January and we cannot guarantee that our data in kivitendo

is locked, that means a booking cannot be modified after a defined (vat tax)

period.

Some validity checks (max_length and regex) will be done if the

data structure contains them and the field is defined.

To add or alter the structure of the data take a look at the C<@kivitendo_to_datev> structure.
