Hello @ajitbooravelli,
Your process seems not to provide the process variable sbRemLtCards.
Can you check that?

The way you reference your DMN is correct. You need to pass a variable sbRemLtCards to the process instance when you start one. You need to start a process instance via REST or Java-API or via Camunda-Tasklist to provide this variable. When starting a process instance from within your modeler there is no way to add a variable.

Best, McAlm
