Here is the code I am invoking it

> .variables(workFlowModelMap)  
> .processDefinitionKey(processInstanceKey)  
> .predefineProcessInstanceId(processInstId)

My engine configuration

> @Bean  
> public MultiSchemaMultiTenantProcessEngineConfiguration processEngineConfigurationImpl() {  
> BankOSTenantHolder tenantInfoHolder= new BankOSTenantHolder();  
> tenantInfoHolder.addTenant(tenants);

```
	MultiSchemaMultiTenantProcessEngineConfiguration config= new MultiSchemaMultiTenantProcessEngineConfiguration(tenantInfoHolder);
	
	config.setDatabaseType(MultiSchemaMultiTenantProcessEngineConfiguration.DATABASE_TYPE_MYSQL);
    config.setDatabaseSchemaUpdate(MultiSchemaMultiTenantProcessEngineConfiguration.DB_SCHEMA_UPDATE_TRUE);
    config.setAsyncExecutorActivate(true);
    config.setDisableIdmEngine(true);
    config.setDisableEventRegistry(true);
    config.setJpaEntityManagerFactory(localContainerEntityManagerFactoryBean.getObject());

    if (sharedExecutor) {
        config.setAsyncExecutor(new SharedExecutorServiceAsyncExecutor(tenantInfoHolder));
    } else {
        config.setAsyncExecutor(new ExecutorPerTenantAsyncExecutor(tenantInfoHolder));
    }
    return config;
}

```
