 The exchange of assets via the EDC takes place after a successful contract negotiation in which it is checked whether the consumer has authorized access to the data asset.
-This access is automatically checked by the EDC via so-called AccessPolicies. The conument is only granted access to the data after a successful check.
+This access is automatically checked by the EDC via so-called AccessPolicies. The consumer is only granted access to the data after a successful check.
+During contract negotation the edc stores audits the following artefacts edc:ContractAgreement and edc:ContractNegotation these audit information could be requested over the edc management api. 
+To request the mentioned artefacts over the management api the ContractAgreementDto:@id is required.
+This specific id must therefore be stored and linked for the exchanged asset in order to be able to determine the corresponding contract agreement later on.
 
 # <ins>Summary</ins> <a name="summary"></a>
 
 # <ins>Problem Statement</ins> <a name="statement"></a>
+1. The ContractAgreementDto:@id is currently not delivered via the IRS response, so business apps that use the IRS cannot access the corresponding ContractAggreement under which the assets delivered by the IRS were exchanged.
+2. The EDC management api does not provide any endpoint to query a contract agreement using an asset id.
+3. Business apps must make the contract agreements under which the assets were exchanged available for audit purposes.
 
 # <ins>Requirements</ins> <a name="requirements"></a>
 
-1. Provisioning of ContractAgreementDto:@id via IRS JobReponse.
+1. [ ] Provisioning of ContractAgreementDto:@id via IRS JobReponse for AAS retrieved via EDC.
+2. [ ] Provisioning of ContractAgreementDto:@id via IRS JobReponse for submodels retrieved via EDC.
+3. [ ] API parameter SHOULD control whether ContractAgreementDto:@id should be returned via the IRSJobResponse

+## ContractAgreementId for submodels 
+
+### Option 1: Provide submodel for  contractAgreementId 
+Impact: High invasive changes to the code, api, JobResponse and documentation. 
+
+```json 
+  "contractAggreements" : [
+    "contractAggreement" : {
+       "contractAgreementId": "<contractAgreementId>",
+       "submodels": [
+        {
+            "identification": "urn:uuid:f9b6f066-c4de-4bed-b531-2a1cad7bd173",
+            "aspectType": "urn:bamm:io.catenax.single_level_bom_as_built:1.0.0#SingleLevelBomAsBuilt",
+            "payload": {
+              <... submodel payload ...>
+        }
+      ] 
+    }     
+
+  ]
+```
+
+### Option 2: Provide contractAgreementId for each submodel: 
+Impact: 
+- Redundant information in case multiple submodels were received for the same contractAgreementId. 
+- JobReponse size is already critical and extends by ~100byte multiples with every submodel and aas shell stored in the JobReponse  
+
+```json 
+	"submodels": [
+
+      {
+        "identification": "urn:uuid:f9b6f066-c4de-4bed-b531-2a1cad7bd173",
+        "aspectType": "urn:bamm:io.catenax.single_level_bom_as_built:1.0.0#SingleLevelBomAsBuilt",
+        "contractAgreementId": "<contractAgreementId>",
+        "payload": {
+            <... submodel payload ...>
