399 SL::GDPDU - IDEA export generator
407 Create new export object. C<PARAMS> may contain:
413 The name of the company, needed for the supplier header
417 Location of the company, needed for the suupplier header
423 Will only include records in the specified date range. Data pulled from other
424 tables will be culled to match what is needed for these records.
428 A list of tables to be exported.
432 Alternative to C<tables>, enables all known tables.
436 =item C<generate_export>
438 Do the work. Will return an absolut path to a temp file where all export files
449 Date format is shit. The official docs state that only C<YY>, C<YYYY>, C<MM>,
450 and C<DD> are supported, timestamps do not exist.
454 Number parsing seems to be fragile. Official docs state that behaviour for too
455 low C<Accuracy> settings is undefined. Accuracy of 0 is not taken to mean
456 Integer but instead generates a warning for redudancy.
458 There is no dedicated integer type.
462 Currently C<ar> and C<ap> have a foreign key to themself with the name
463 C<storno_id>. If this foreign key is present in the C<INDEX.XML> then the
464 storno records have to be too. Since this is extremely awkward to code and
465 confusing for the examiner as to why there are records outside of the time
466 range, this export skips all self-referential foreign keys.
470 Documentation for foreign keys is extremely weird. Instead of giving column
471 maps it assumes that foreign keys map to the primary keys given for the target
472 table, and in that order. Foreign keys to keys that are not primary seems to be
473 impossible. Changing type is also not allowed (which actually makes sense).
474 Hopefully there are no bugs there.
478 It's currently disallowed to export the whole dataset. It's not clear if this
483 It is not possible to set an empty C<DigiGroupingSymbol> since then the import
484 will just work with the default. This was asked in their forum, and the
485 response actually was:
487 Einfache Lösung: Definieren Sie das Tausendertrennzeichen als Komma, auch
488 wenn es nicht verwendet wird. Sollten Sie das Komma bereits als Feldtrenner
489 verwenden, so wählen Sie als Tausendertrennzeichen eine Alternative wie das
492 L<http://www.gdpdu-portal.com/forum/index.php?mode=thread&id=1392>
496 It is not possible to define a C<RecordDelimiter> with XML entities. 

497 generates the error message:
499 C<RecordDelimiter>-Wert (
) sollte immer aus ein oder zwei Zeichen
502 Instead we just use the implicit default RecordDelimiter CRLF.
508 Foreign keys seem only to work with previously defined tables (which would be
