1089 This module implements the DATEV export standard. For usage see above.
1097 Generic constructor. See section attributes for information about hat to pass.
1099 =item get_datev_stamm
1101 Loads DATEV Stammdaten and returns as hashref.
1103 =item save_datev_stamm HASHREF
1105 Saves DATEV Stammdaten from provided hashref.
1109 See L<CONSTANTS> for possible values
1111 =item has_exporttype
1113 Returns true if an exporttype has been set. Without exporttype most report functions won't work.
1117 Specifies the designated format of the export. Currently only KNE export is implemented.
1119 See L<CONSTANTS> for possible values
1123 Returns true if a format has been set. Without format most report functions won't work.
1125 =item download_token
1127 Returns a download token for this DATEV object.
1129 Note: If either a download_token or export_path were set at the creation these are infered, otherwise randomly generated.
1133 Returns an export_path for this DATEV object.
1135 Note: If either a download_token or export_path were set at the creation these are infered, otherwise randomly generated.
1139 Returns a list of filenames generated by this DATEV object. This only works if th files were generated during it's lifetime, not if the object was created from a download_token.
1141 =item net_gross_differences
1143 If there were any net gross differences during calculation they will be collected here.
1145 =item sum_net_gross_differences
1147 Sum of all differences.
1149 =item clean_temporary_directories
1151 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.
1155 Returns a list of errors that occured. If no errors occured, the export was a success.
1159 Exports data. You have to have set L<exporttype> and L<format> or an error will
1160 occur. OBE exports are currently not implemented.
1166 This is a list of attributes set in either the C<new> or a method of the same name.
1172 Set a database handle to use in the process. This allows for an export to be
1173 done on a transaction in progress without committing first.
1177 See L<CONSTANTS> for possible values. This MUST be set before export is called.
1181 See L<CONSTANTS> for possible values. This MUST be set before export is called.
1183 =item download_token
1185 Can be set on creation to retrieve a prior export for download.
1191 Set boundary dates for the export. Currently thse MUST be set for the export to work.
1197 Set boundary account numbers for the export. Only useful for a stammdaten export.
1203 =head2 Supplied to L<exporttype>
1207 =item DATEV_ET_BUCHUNGEN
1209 =item DATEV_ET_STAMM
1213 =head2 Supplied to L<format>.
1217 =item DATEV_FORMAT_KNE
1219 =item DATEV_FORMAT_OBE
1223 =head1 ERROR HANDLING
1225 This module will die in the following cases:
1231 No or unrecognized exporttype or format was provided for an export
1235 OBE rxport was called, which is not yet implemented.
1243 Errors that occur during th actual export will be collected in L<errors>. The following types can occur at the moment:
1249 C<Unbalanced Ledger!>. Exactly that, your ledger is unbalanced. Should never occur.
1253 C<Datev-Export fehlgeschlagen! Bei Transaktion %d (%f).> This error occurs if a
1254 transaction could not be reliably sorted out, or had rounding errors over the acceptable threshold.
1258 =head1 BUGS AND CAVEATS
1264 Handling of Vollvorlauf is currently not fully implemented. You must provide both from and to to get a working export.
1268 OBE export is currently not implemented.
1274 - handling of export_path and download token is a bit dodgy, clean that up.
