1544 This module implements the DATEV export standard. For usage see above.
1552 Generic constructor. See section attributes for information about what to pass.
1554 =item generate_datev_data
1556 Fetches all transactions from the database (via a trans_id or a date range),
1557 and does an initial transformation (e.g. filters out tax, determines
1558 the brutto amount, checks split transactions ...) and stores this data in
1561 If any errors are found these are collected in $self->errors.
1563 This function is needed for all the exports, but can be also called
1564 independently in order to check transactions for DATEV compatibility.
1566 =item generate_datev_lines
1568 Parse the data in $self->{DATEV} and transform it into a format that can be
1569 used by DATEV, e.g. determines Konto and Gegenkonto, the taxkey, ...
1571 The transformed data is returned as an arrayref, which is ready to be converted
1572 to a DATEV data format, e.g. KNE, OBE, CSV, ...
1574 At this stage the "DATEV rule" has already been applied to the taxkeys, i.e.
1575 entries with datevautomatik have an empty taxkey, as the taxkey is already
1576 determined by the chart.
1578 =item get_datev_stamm
1580 Loads DATEV Stammdaten and returns as hashref.
1582 =item save_datev_stamm HASHREF
1584 Saves DATEV Stammdaten from provided hashref.
1588 See L<CONSTANTS> for possible values
1590 =item has_exporttype
1592 Returns true if an exporttype has been set. Without exporttype most report functions won't work.
1596 Specifies the designated format of the export. Currently only KNE export is implemented.
1598 See L<CONSTANTS> for possible values
1602 Returns true if a format has been set. Without format most report functions won't work.
1604 =item download_token
1606 Returns a download token for this DATEV object.
1608 Note: If either a download_token or export_path were set at the creation these are infered, otherwise randomly generated.
1612 Returns an export_path for this DATEV object.
1614 Note: If either a download_token or export_path were set at the creation these are infered, otherwise randomly generated.
1618 Returns a list of filenames generated by this DATEV object. This only works if the files were generated during its lifetime, not if the object was created from a download_token.
1620 =item net_gross_differences
1622 If there were any net gross differences during calculation they will be collected here.
1624 =item sum_net_gross_differences
1626 Sum of all differences.
1628 =item clean_temporary_directories
1630 Forces a garbage collection on previous exports which will delete all exports that are older than 8 hours. It will be automatically called on destruction of the object, but is advised to be called manually before delivering results of an export to the user.
1634 Returns a list of errors that occured. If no errors occured, the export was a success.
1638 Exports data. You have to have set L<exporttype> and L<format> or an error will
1639 occur. OBE exports are currently not implemented.
1641 =item csv_export_for_tax_accountant
1643 Generates up to four downloadable csv files containing data about sales and
1644 purchase invoices, and their respective payments:
1647 my $startdate = DateTime->new(year => 2012, month => 1, day => 1);
1648 my $enddate = DateTime->new(year => 2012, month => 12, day => 31);
1649 SL::DATEV->new(from => $startdate, to => $enddate)->csv_export_for_tax_accountant;
1651 # 'download_token' => '1488551625-815654-22430',
1653 # 'Zahlungen Kreditorenbuchungen 2012-01-01 - 2012-12-31.csv',
1654 # 'Kreditorenbuchungen 2012-01-01 - 2012-12-31.csv',
1655 # 'Zahlungen Debitorenbuchungen 2012-01-01 - 2012-12-31.csv',
1656 # 'Debitorenbuchungen 2012-01-01 - 2012-12-31.csv'
1661 =item check_vcnumbers_are_valid_pk_numbers
1663 Returns 1 if all vcnumbers are suitable for the DATEV export, 0 if not.
1665 Finds the default length of charts (e.g. 4), adds 1 for the pk chart length
1666 (e.g. 5), and checks the database for any customers or vendors whose customer-
1667 or vendornumber doesn't consist of only numbers with exactly that length. E.g.
1668 for a chart length of four "10001" would be ok, but not "10001b" or "1000".
1670 All vcnumbers are checked, obsolete customers or vendors aren't exempt.
1672 There is also no check for the typical customer range 10000-69999 and the
1673 typical vendor range 70000-99999.
1675 =item check_valid_length_of_accounts
1677 Returns 1 if all currently booked accounts have only one common number length domain (e.g. 4 or 6).
1678 Will throw an error if more than one distinct size is detected.
1679 The error message gives a short hint with the value of the (at least)
1680 two mismatching number length domains.
1686 This is a list of attributes set in either the C<new> or a method of the same name.
1692 Set a database handle to use in the process. This allows for an export to be
1693 done on a transaction in progress without committing first.
1695 Note: If you don't want this code to commit, simply providing a dbh is not
1696 enough enymore. You'll have to wrap the call into a transaction yourself, so
1697 that the internal transaction does not commit.
1701 See L<CONSTANTS> for possible values. This MUST be set before export is called.
1705 See L<CONSTANTS> for possible values. This MUST be set before export is called.
1707 =item download_token
1709 Can be set on creation to retrieve a prior export for download.
1715 Set boundary dates for the export. Unless a trans_id is passed these MUST be
1716 set for the export to work.
1720 To check only one gl/ar/ap transaction, pass the trans_id. The attributes
1721 L<from> and L<to> are currently still needed for the query to be assembled
1728 Set boundary account numbers for the export. Only useful for a stammdaten export.
1732 Boolean if the transactions are locked (read-only in kivitenod) or not.
1733 Default value is false
1739 =head2 Supplied to L<exporttype>
1743 =item DATEV_ET_BUCHUNGEN
1745 =item DATEV_ET_STAMM
1749 =head2 Supplied to L<format>.

1759 =head1 ERROR HANDLING
1761 This module will die in the following cases:
1767 No or unrecognized exporttype or format was provided for an export
1771 OBE export was called, which is not yet implemented.
1779 Errors that occur during th actual export will be collected in L<errors>. The following types can occur at the moment:
1785 C<Unbalanced Ledger!>. Exactly that, your ledger is unbalanced. Should never occur.
1789 C<Datev-Export fehlgeschlagen! Bei Transaktion %d (%f).> This error occurs if a
1790 transaction could not be reliably sorted out, or had rounding errors above the acceptable threshold.
1794 =head1 BUGS AND CAVEATS
1800 Handling of Vollvorlauf is currently not fully implemented. You must provide both from and to in order to get a working export.
1804 OBE export is currently not implemented.
1810 - handling of export_path and download token is a bit dodgy, clean that up.
