IBP CPI-DS ABAP Options Filter

Hi All,

is there a possibility in CPI-DS Abap Options to use Global Variables that contain a list of variables within a single global variable like '\'filter2\',\'filter2\'' ?

If I try '\'filter2\',\'filter2\'' for a varchar global variable in filters, i got error:
ABAP SYNTAX ERROR Nach "''" wurde ".", "LENGTH ..." oder "DECIMALS ..." erwarte>.

Thanks & Regards
Benjamin
