  41  * This Generic sub flow can be used by any flow for the

  43  * this sub flow the GENPS_SuccessIndicator will be true.
  44  * The calling flow must set the GENPS_type variable as "service-instance"
  45  * or "service-subscription".
  46  *  A MSOWorkflowException will be thrown Upon unsuccessful
  47  * completion or if an error occurs within this flow.
  48  * Please map variables to the corresponding variable names
  49  * below.

  52  * Incoming Required Variables:

  56  * @param - GENPS_serviceType - Required Field
  57  * @param - GENPS_payload - Required Field This will be the payload that needs to be sent.
  58  *
  59  * @param - GENPS_serviceInstanceId - Conditional Field. Required for service-instance.
  60  * @param - GENPS_allottedResourceId - Conditional Field. Required for allotted-resource.

  62  *
  63  * @param - GENPS_serviceResourceVersion - Conditional Field. Needs to be provided only in case of update for both service-instance and service subscription. The calling flows
  64  *          should check if a service-instance or servic-subscription exists by calling the subflow GenericGetService. if it exists then resourceversion should be
  65  *          obtained from aai and sent as an input parameter.
