troubles with linking subreport with an SAP Query variable
I have a main report mith a subreport placed in the detail section.
Both reports base on an Bex Query and have Query-variables. While linking the subreport i can not select the parameter which is based on the Bex variable in the subreport.
While connecting other parameters /variables i learned, that Crystal cannot determine the type of data of a Bex variable, right?
Because of that i built formulas which convert my values into strings and these strings can i connect in the subreport linking.
Unforntunately this does not work with this on variable. In Bex this is a Number. I tried to link with the corresponding field in the Detail section (which is a number, too) and i tried with the string, but both does not work. I can not select this Parameter.
Any idea how to determine the datatype of this Parameter (based on Bex Variable) i have to provide?
Thanks in advance
