|
=head1 DESCRIPTION
|
|
|
|
The parsing of the DATEV CSV is index based, therefore the correct
|
|
column must be present at the corresponding index, i.e.:
|
|
Index 2
|
|
Field Name : Debit/Credit Label
|
|
Valid Values : 'S' or 'H'
|
|
Length: : 1
|
|
|
|
The columns in C<@kivi_datev> are in the correct order and the
|
|
specific attributes are defined as a key value hash list for each entry.
|
|
|
|
The key names are the english translation according to the DATEV specs
|
|
(Leitfaden DATEV englisch).
|
|
|
|
The two attributes C<max_length> and C<type> are also set as specified
|
|
by the DATEV specs.
|
|
|
|
To link the structure to kivitendo data, each entry has the attribute C<kivi_datev_name>
|
|
which is by convention the key name as generated by DATEV->generate_datev_data.
|
|
A value of C<'not yet implemented'> indicates that this field has no
|
|
corresponding kivitendo data and will be given an empty value by DATEV->csv_buchungsexport.
|
|
|
|
|
|
=head1 SPECIFICATION
|
|
|
|
This is an excerpt of the DATEV Format 2015 Specification for CSV-Header
|
|
and CSV-Data lines.
|
|
|
|
=head2 FILENAME
|
|
|
|
The filename is subject to the following restrictions:
|
|
1. The filename must begin with the prefix DTVF_ or EXTF_.
|
|
2. The filename must end with .csv.
|
|
|
|
When exporting from or importing into DATEV applications, the filename is
|
|
marked with the prefix "DTVF_" (DATEV Format).
|
|
The prefix "DTVF_" is reserved for DATEV applications.
|
|
If you are using a third-party application to create a file in the DATEV format
|
|
that you want to import using batch processing, use the prefix "EXTF_"
|
|
(External Format).
|
|
|
|
=head2 File Structure
|
|
|
|
The file structure of the text file exported/imported is defined as follows
|
|
|
|
Line 1: Header (serves to assist in the interpretation of the following data)
|
|
|
|
Line 2: Headline (headline of the user data)
|
|
|
|
Line 3 – n: Records (user data)
|
|
|
|
For an valid example file take a look at doc/DATEV-2015/EXTF_Buchungsstapel.csv
|
|
|
|
|
|
=head2 Detailed Description
|
|
|
|
Line 1 must contain 11 fields.
|
|
|
|
Line 2 must contain 26 fields.
|
|
|
|
Line 3 - n: must contain 116 fields, a smaller subset is mandatory.
|
|
|
|
=head1 FUNCTIONS
|
|
|
|
=over 4
|
|
|
|
=item new PARAMS
|
|
|
|
Constructor for CSV-DATEV export.
|
|
Checks mandantory params as described in section synopsis.
|
|
|
|
=item check_encoding
|
|
|
|
Helper function, returns true if a string is not empty and cp1252 encoded
|
|
For example some arabic utf-8 like ݐ will return false
|
|
|
|
=item header
|
|
|
|
Mostly all other header information are constants or metadata loaded
|
|
from SL::DB::Datev.pm.
|
|
|
|
Returns the first two entries for the header (see above: File Structure)
|
|
as an array.
|
|
|
|
=item kivitendo_to_datev
|
|
|
|
Returns the data structure C<@datev_data> as an array
|
|
|
|
=item _format_amount
|
|
|
|
Lightweight wrapper for form->format_amount.
|
|
Expects a number in kivitendo database format and returns the same number
|
|
in DATEV format.
|
|
|
|
=item first_day_of_fiscal_year
|
|
|
|
Takes a look at $self->to to determine the first day of the fiscal year.
|
|
|
|
=item lines
|
|
|
|
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.

=head1 TODO CAVEAT
|
|
|
|
One can circumevent the check of the warnings.quite easily,
|
|
becaus warnings are generated after the call to lines:
|
|
|
|
# WRONG usage
|
|
die if @{ $datev_csv->warnings };
|
|
somethin_with($datev_csv->lines);
|
|
|
|
# safe usage
|
|
my $lines = $datev_csv->lines;
|
|
die if @{ $datev_csv->warnings };
|
|
somethin_with($lines);
|
