399 $datev_csv->lines; # returns an array_ref of rows of array_refs soll uns die ein Arrayref von Zeilen zurückgeben, die jeweils Arrayrefs sind
400 $datev_csv->warnings; # returns warnings
403 # The above object methods can be directly chained to a CSV export function, like this:
404 my $csv_file = IO::File->new($somewhere_in_filesystem)') or die "Can't open: $!";

406 $csv->print($csv_file, $_) for @{ $datev_csv->lines };
408 $self->{warnings} = $datev_csv->warnings;
415 The parsing of the DATEV CSV is index based, therefore the correct
416 column must be present at the corresponding index, i.e.:
418 Field Name : Debit/Credit Label
419 Valid Values : 'S' or 'H'
422 The columns in C<@kivi_datev> are in the correct order and the
423 specific attributes are defined as a key value hash list for each entry.
425 The key names are the english translation according to the DATEV specs
426 (Leitfaden DATEV englisch).
428 The two attributes C<max_length> and C<type> are also set as specified
431 To link the structure to kivitendo data, each entry has the attribute C<kivi_datev_name>
432 which is by convention the key name as generated by DATEV->generate_datev_data.
433 A value of C<'not yet implemented'> indicates that this field has no
434 corresponding kivitendo data and will be given an empty value by DATEV->csv_buchungsexport.
439 This is an excerpt of the DATEV Format 2015 Specification for CSV-Header
444 The filename is subject to the following restrictions:
445 1. The filename must begin with the prefix DTVF_ or EXTF_.
446 2. The filename must end with .csv.
448 When exporting from or importing into DATEV applications, the filename is
449 marked with the prefix "DTVF_" (DATEV Format).
450 The prefix "DTVF_" is reserved for DATEV applications.
451 If you are using a third-party application to create a file in the DATEV format
452 that you want to import using batch processing, use the prefix "EXTF_"
455 =head2 File Structure
457 The file structure of the text file exported/imported is defined as follows
459 Line 1: Header (serves to assist in the interpretation of the following data)
461 Line 2: Headline (headline of the user data)
463 Line 3 – n: Records (user data)
465 For an valid example file take a look at doc/DATEV-2015/EXTF_Buchungsstapel.csv
468 =head2 Detailed Description
470 Line 1 must contain 11 fields.
472 Line 2 must contain 26 fields.
474 Line 3 - n: must contain 116 fields, a smaller subset is mandatory.
482 Constructor for CSV-DATEV export.
483 Checks mandantory params as described in section synopsis.
487 Helper function, returns true if a string is not empty and cp1252 encoded
488 For example some arabic utf-8 like ݐ will return false
492 Mostly all other header information are constants or metadata loaded
493 from SL::DB::Datev.pm.
495 Returns the first two entries for the header (see above: File Structure)
498 =item kivitendo_to_datev
500 Returns the data structure C<@datev_data> as an array
504 Lightweight wrapper for form->format_amount.
505 Expects a number in kivitendo database format and returns the same number
508 =item first_day_of_fiscal_year
510 Takes a look at $self->to to determine the first day of the fiscal year.
514 Generates the CSV-Format data for the CSV DATEV export and returns
515 an 2-dimensional array as an array_ref.
516 May additionally return a second array_ref with warnings.
518 Requires the same date fields as the constructor for a valid DATEV header.
520 Furthermore we assume that the first day of the fiscal year is
521 the first of January and we cannot guarantee that our data in kivitendo
522 is locked, that means a booking cannot be modified after a defined (vat tax)
524 Some validity checks (max_length and regex) will be done if the
525 data structure contains them and the field is defined.
527 To add or alter the structure of the data take a look at the C<@kivitendo_to_datev> structure.
533 One can circumevent the check of the warnings.quite easily,
534 becaus warnings are generated after the call to lines:
537 die if @{ $datev_csv->warnings };
538 somethin_with($datev_csv->lines);
541 my $lines = $datev_csv->lines;
542 die if @{ $datev_csv->warnings };
543 somethin_with($lines);
