Hi all,

I'm wondering if is possible to call to a BO from a HL7 Route according to a parameter of the HL7 Message

I mean,

According to the identify of the laboratory, I want to call to other TCP process to retrieve information about blood tests.

We are creating the BO using this partern.

LAB.BO.TCP. + name of the laboratory.

The name of the laboratory is stoted in the lookup table T_LABORATORIOS

I've tried to assign the name into a variable and put it in the "send" instruction, but it doesn't work.

is it possible to call to a BO by a text variable instead of seleccting the BO from the production?

Our prodution will have more laboratories and we want to create a rule common for all of them

Best regards,

Kurro Lopez

I don't think dynamic return value is possible.

As a workaround you can write the desired destination value in context and redefine doOneAction in your custom router engine to replace i.e. @destino value with a value from a context before calling ##super.

@Eduard Lebedyuk is correct (yeah, he's always correct 😁), you can't use a variable for the target in a business rule.

You can do this in a custom BP (COS or Python) or a BPL-based BP, though. The BPL <call> action specifically supports a context variable as a destination:

The variable would be assigned the name of the BH to send to prior to invoking the call.

Thanks, it is our Plan B... we're going to create a BP that calls to the provider and uses the variable.

Great answer, thanks mates
