658 $datev_csv->warnings; # returns warnings
661 # The above object methods can be directly chained to a CSV export function, like this:
662 my $csv_file = IO::File->new($somewhere_in_filesystem)') or die "Can't open: $!";

664 $csv->print($csv_file, $_) for @{ $datev_csv->lines };
666 $self->{warnings} = $datev_csv->warnings;
673 The parsing of the DATEV CSV is index based, therefore the correct
674 column must be present at the corresponding index, i.e.:
676 Field Name : Debit/Credit Label
677 Valid Values : 'S' or 'H'
680 The columns in C<@kivi_datev> are in the correct order and the
681 specific attributes are defined as a key value hash list for each entry.
683 The key names are the english translation according to the DATEV specs
684 (Leitfaden DATEV englisch).
686 The two attributes C<max_length> and C<type> are also set as specified
689 To link the structure to kivitendo data, each entry has the attribute C<kivi_datev_name>
690 which is by convention the key name as generated by DATEV->generate_datev_data.
691 A value of C<'not yet implemented'> indicates that this field has no
692 corresponding kivitendo data and will be given an empty value by DATEV->csv_buchungsexport.
697 This is an excerpt of the DATEV Format 2015 Specification for CSV-Header
702 The filename is subject to the following restrictions:
703 1. The filename must begin with the prefix DTVF_ or EXTF_.
704 2. The filename must end with .csv.
706 When exporting from or importing into DATEV applications, the filename is
707 marked with the prefix "DTVF_" (DATEV Format).
708 The prefix "DTVF_" is reserved for DATEV applications.
709 If you are using a third-party application to create a file in the DATEV format
710 that you want to import using batch processing, use the prefix "EXTF_"
713 =head2 File Structure
715 The file structure of the text file exported/imported is defined as follows
717 Line 1: Header (serves to assist in the interpretation of the following data)
719 Line 2: Headline (headline of the user data)
721 Line 3 – n: Records (user data)
723 For an valid example file take a look at doc/DATEV-2015/EXTF_Buchungsstapel.csv
726 =head2 Detailed Description
728 Line 1 must contain 11 fields.
730 Line 2 must contain 26 fields.
732 Line 3 - n: must contain 116 fields, a smaller subset is mandatory.
740 Constructor for CSV-DATEV export.
741 Checks mandantory params as described in section synopsis.
745 Helper function, returns true if a string is not empty and cp1252 encoded
746 For example some arabic utf-8 like ݐ will return false
750 Mostly all other header information are constants or metadata loaded
751 from SL::DB::Datev.pm.
753 Returns the first two entries for the header (see above: File Structure)
756 =item kivitendo_to_datev
758 Returns the data structure C<@datev_data> as an array
762 Lightweight wrapper for form->format_amount.
763 Expects a number in kivitendo database format and returns the same number
766 =item first_day_of_fiscal_year
768 Takes a look at $self->to to determine the first day of the fiscal year.
772 Generates the CSV-Format data for the CSV DATEV export and returns
773 an 2-dimensional array as an array_ref.
774 May additionally return a second array_ref with warnings.
776 Requires the same date fields as the constructor for a valid DATEV header.
778 Furthermore we assume that the first day of the fiscal year is
779 the first of January and we cannot guarantee that our data in kivitendo
780 is locked, that means a booking cannot be modified after a defined (vat tax)
782 Some validity checks (max_length and regex) will be done if the
783 data structure contains them and the field is defined.
785 To add or alter the structure of the data take a look at the C<@kivitendo_to_datev> structure.
791 One can circumevent the check of the warnings.quite easily,
792 becaus warnings are generated after the call to lines:
795 die if @{ $datev_csv->warnings };
796 somethin_with($datev_csv->lines);
799 my $lines = $datev_csv->lines;
800 die if @{ $datev_csv->warnings };
801 somethin_with($lines);
