Using the SAP Business Accelerator Hub ‘Try Out’ section I have failed to filter accountingdocuments using the ‘LastChangeDate’ property value. While filtering by text property values like ‘AccountingDocument’ works as expected.

Link to SAP to try out the API: https://api.sap.com/api/API_OPLACCTGDOCITEMCUBE_SRV/tryout

https://sandbox.api.sap.com/s4hanacloud/sap/opu/odata/sap/API_OPLACCTGDOCITEMCUBE_SRV/A_OperationalAcctgDocItemCube?$top=50&$filter=AccountingDocument%20eq%20'100000032'&$inlinecount=allpages

The request above will return the response below. (The original response is a lot bigger, I have shortened it with only the important fields.)

{
    "__metadata": {
      "id": "https://sandbox.api.sap.com/s4hanacloud/sap/opu/odata/sap/API_OPLACCTGDOCITEMCUBE_SRV/A_OperationalAcctgDocItemCube(CompanyCode='1010',FiscalYear='2015',AccountingDocument='100000032',AccountingDocumentItem='1')",
      "uri": "https://sandbox.api.sap.com/s4hanacloud/sap/opu/odata/sap/API_OPLACCTGDOCITEMCUBE_SRV/A_OperationalAcctgDocItemCube(CompanyCode='1010',FiscalYear='2015',AccountingDocument='100000032',AccountingDocumentItem='1')",
      "type": "API_OPLACCTGDOCITEMCUBE_SRV.A_OperationalAcctgDocItemCubeType"
    },
    "CompanyCode": "1010",
    "FiscalYear": "2015",
    "AccountingDocument": "100000032",
    "LastChangeDate": "/Date(1502841600000)/",
}```

As you can see the LastChangeDate of this AccountingDocument is '/Date(1502841600000)/'.
Using this data I assumed the following request would give me the response I am looking for.

https://sandbox.api.sap.com/s4hanacloud/sap/opu/odata/sap/API_OPLACCTGDOCITEMCUBE_SRV/A_OperationalAcctgDocItemCube?$top=50&$filter=LastChangeDate%20eq%20’%2FDate(1502841600000)%2F’&$inlinecount=allpages

[This is the response I get, which is basically a 400 bad request.](https://i.sstatic.net/LRvSVpkd.png)


Is it possible to do what I am trying?
