I attach the Code of DMN file Here.

HI Darshan,

I created a project using springboot, your models, and the drools libraries with the version you mention.
I could not recreate the issue, so the models by themselves seem correct, and also the core-code seems to work.
I suspect there could be some issue in your project setup (Dependencies ? Invocations ?), but just guessing.

If you could share it, or a modified version that shows the unexpected behaviour, I would be glad to take a look at it.

Hi I share all Dependency below that I use my Spring boot Project

<dependency>

   <artifactId>groovy-all</artifactId>
   <version>3.0.18</version>
   <type>pom</type>
</dependency>
<dependency>
   <groupId>org.drools</groupId>
   <artifactId>drools-engine-classic</artifactId>
</dependency>
<dependency>
   <groupId>org.kie</groupId>
   <artifactId>kie-dmn-core</artifactId>
   <version>${drools-version}</version>
</dependency>
<dependency>

hi ,

Standalone DMN file run successfully and I get the DMN Result but when I Import one file to another file then we get status skipped.

Can you please tell the meaning of Skipped status.

Thanks

Darshan

[Gabriele Cardosi]

HI Darshan,
"SKIPPED" simply means that, for whatever reason, the decision could not be evaluated.
The very first thing to verify is that the engine receives the correct input data - i.e. that suche data is put inside DMN "context".
How this is achieved depends on the implementations, and could be a matter of missing code, or some serialization issue, or whatever - can't tell only from the list of dependencies.
After double checked that

1. correct input is sent to the code that invokes the engine
2. correct input is actually put in the context before evaluation
   

there could be some strange situations I currently can't think about

Hope this help

Hi 

Yes You are right,

This Both file Run Successfully on KieSandBox link is Here

But when I run with Java No any Exception Thrown by Drools just give Skipped Status.

Thanks

Hi Darshan,

without a full reproducer (i.e. the whole project) I can't be of much more help.
Please share one, if possible, so that I can have a better understanding.

Hi,

I get the below Error message in Java Code base where I evaluate the DMN file. can you please explain.

On Kie Sandbox  Not faced any error.

Required dependency 'COAPPLICANT_DETAIL' not found on node 'ENRICHED_PARAMS_FOR_COAPP'

Thanks & Regards

[Gabriele Cardosi]

HI Darshan

sorry, but as I said before I can not help in any way without the code you are actually using - even a strimmed/modified version that anyway shows the problem.
1. The Kie Sandbox does not show any error and, as per my private tests, those models are valid
2. without knowing where the "Required dependency 'COAPPLICANT_DETAIL' not found on node 'ENRICHED_PARAMS_FOR_COAPP'" comes from, how the java code consume the models, etc etc, I can not tell you what's going on
3. I could not find reference on such strings on the DMNs you shared
4. The only thing that I could imagine is that some ENRICHED_PARAMS_FOR_COAPP "item" requires a "COAPPLICANT_DETAIL" item that it is not in the compilation context

I would be glad to help, but I have the impression it all depends on the actual models and java code you are using...
