Rawtype have two values (1 or 2). So above expression I want to write only for Rawtype value equal to 1.

Hi,

 tuple Raw
{
key int Rawtype;
float Rawamount;
}

tuple t
{
int Rawtype;
float Rawreq;
}

{Raw} RawAvail = {<1,2.0>,<2,3.0>};;

{t} Rawperprocess ={<1,3.0>,<1,4.8>,<2,3.0>};

 

dexpr float rawConsume[r in RawAvail] = sum ( dr in Rawperprocess:dr.Rawtype == r.Rawtype)(dr.Rawreq*1000);

subject to
{

}

execute
{
writeln(rawConsume);;
}

gives

[7800 3000]
