Escaping of apostrophe in variables with multiple values DS 1.5

Hi All,

we encountered with strange behaviour of DS 1.5 when DS 1.5 transmits variables values to HANA. Test example:

1. We set a variable value in a HANA Calculation View according to this document:

     APPLICATION.setVariableValueExt("I_SALES_GRP_VAL", "041'',''042");

2. Debug it in DS 1.5 client:

[BICS HANA](102ms) SQL:SELECT "SALES_GRP_TXTSH", SUM("COUNTER") as "COUNTER" FROM "_SYS_BIC"."D00_DS_GENERAL.M_CLCV_10"  GROUP BY GROUPING SETS WITH SUBTOTAL STRUCTURED RESULT WITH OVERVIEW PREFIX '#BICS_1434463642382_' ((("SALES_GRP_TXTSH") ORDER BY "SALES_GRP_TXTSH" ASC )) WITH PARAMETERS ('PLACEHOLDER' = ('$$I_SALES_GRP_VAL$$','041\''\'',\''\''042'))

3.Debug it in DS 1.4 client:

[BICS HANA](124ms) SQL:SELECT "SALES_GRP_TXTSH", SUM("COUNTER") as "COUNTER" FROM "_SYS_BIC"."D00_DS_GENERAL.M_CLCV_10"  GROUP BY GROUPING SETS WITH SUBTOTAL STRUCTURED RESULT WITH OVERVIEW PREFIX '#BICS_1434463686339_' ((("SALES_GRP_TXTSH") ORDER BY "SALES_GRP_TXTSH" ASC )) WITH PARAMETERS ('PLACEHOLDER' = ('$$I_SALES_GRP_VAL$$','041'',''042'))

So, our DS reports with multiple input parameters work fine in DS 1.4 Local mode but don't operate correctly in DS 1.5 Local mode or DS 1.5 BI Platform mode.

Any ideas how to fix this transformation of variables values?

Many thanks in advance,

Dmitry.
