HI all,
Many thanks for the swift response. Unfortunately I have just tried several attempts and cannot get this working (while the meter runs on AWS, yikes).
If I use the following projection filter syntax as Henrique suggest, which would seem as per the CE_CALC example in the SQLscript guide, it should be :
' "QuantityUnit" = '':quantityitem'' ');
where I have single quote, double quote, table field, double quote, equals, single quote single quote, colon, input parameter, single quote single quote single quote (then followed by closing bracket and semi-colon) I get the input parameter highlighted in red with message "syntax error: "':quantityitem'" is incorrect or misplaced. Of course I can commit but activation fails.
