**\[Issue\]:** "GET status information about multiple VNF LCM Operation OCC" VNF LCM OP OCC, test case fails during validation of VnfLcmOpOccs schema json. **\[Issue Detail\]** ·       Executed “GET status information about multiple VNF LCM Operation OCC” compliance test in Tacker. ·       **Sol_compliance:** SOL003 ·       **API:** VNFLifecycleManagement-API ·       **Robot File:** VnfLcmOperationOccurences.robot ·       **Testcase Title:** GET status information about multiple VNF LCM Operation OCC ·       **Test ID:** 7.3.1.11.2 ·       **Error message:** \<status status="FAIL" starttime="20241016 04:58:04.977" endtime="20241016 04:58:05.908" critical="yes"\>ValidationError: Validation error for schema VnfLcmOpOccs.schema.json: 'operationParams' is a required property\</status\> ·       **Error location:** https://forge.etsi.org/rep/nfv/api-tests/-/blob/2.6.1-fix-plu/SOL003/VNFLifecycleManagement-API/schemas/VnfLcmOpOccs.schema.json **\[Cause\]** Note: As per our understanding, if a parameter has cardinality 0..1, it is not a required parameter. Required parameter has cardinality 1. ·       As per ETSI specification, ‘operationParams’ has cardinality 0..1 which means it is not a required parameter but, in VnfLcmOpOccs schema json, ‘operationParams’ is in required parameters list. Thus, testcase gets failed during validation because ‘operationParams’ is not present in Tacker’s output response. **\[Fix Proposal\]** ·       Correct VnfLcmOpOccs schema json and remove ‘operationParams’ from required parameters list in SOL003 v2.6.1-fix-plu branch.
