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.
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.
