* Feature: Enable custom converters
Added method get_supported_class to ZIF_EXCEL_CONVERTER.
Implement your own converter by implementing this interface
and tell via the new interface method which class you support.
All instanceable implementations of the interface will be found
automatically.
* Fix abapLint issues
A cell contained text in the original template. It was lated deleted. But apparently a link to SharedStrings from the cell was not removed. An exception occurred after downloading and opening the file via ZCL_EXCELL_READER_2007 class. All operations until ZCL_EXCEL_READER_2007 were done using other tools.
* ATC check cleared
removed SELECT * from USR01
removed empty SELECT...ENDSELECT on URS01
* Removed Inerface method implementation
ZIF_EXCEL_READER~CAN_READ_FILE was implemented but this method is not defined anymore in the Interface.
ATC check failed with incorrect syntax.
Solution: Method implementation deleted.
according to the SAP note 1750204 we can use the method IF_IXML_OSTREAM->SKIP_NON_XML_CHARACTERS to strip out illegal characters for XML rendering.
Since this method needs a kernel version with builtin support, I've made the call dynamically in a try/catch block to support systems with a lower kernel too.
This patch fixes the issues from #298 (at least for us)
* Update zcl_excel_worksheet.clas.abap
Allow int8 type columns
* Option to create empty file
Allow to create empty excel file even if input table is empty
* Update zcl_excel_worksheet.clas.abap
Add the option to create the file or not if the input table is empty
* Test report zdemo_excel43
When using CSV mainly, if the input table is empty, the csv file contained a line with empty fields and separators.
This fooled some automation process thinking there's data to process in the file.
When optional input parameter "iv_no_line_if_empty" of method "zcl_excel_worksheet->bind_table" is checked, there's no more empty line in this case.
* User demo report 44 instead of 43
Mistake in test program name
* Fix internal renaming of test report 44
* Correct filename and test both cases
* Include test 44
When reading xlsx and autofilters are being applied a dump occured when autofilter range was defined like "Sheet1!#REF1"
Such ranges are now ignored so that the xlsx can be read.
