Hi, According SOL002 v2.6.1 §5.4.3.3.4 The method PATCH exists. Note that the patch method is using a vnfLcmOpOccId > Patch ${apiRoot}/${apiName}/${apiVersion}/vnf_instances/${vnfLcmOpOccId} According SOL002 v2.6.1 §5.4.3.3.5 The method DELETE exists. And same strange Id > Delete ${apiRoot}/${apiName}/${apiVersion}/vnf_instances/${vnfLcmOpOccId}
