How to use filter for Sage300 Web API data by Optional fields value?

Hi Expert ,

    I am currently using Customer / OEOrders / OEInvoices  webapi . I have added some custom fields . I want to filter data using that custom field through Sage300 WebApi .Below is example i am trying to filter :

     

                     itsl-sage/.../OEOrders eq 110
                      showing below error : 
                             
{
  "error": {
    "code": "InvalidParameters",
    "message": {
      "lang": "en-US",
      "value": "Syntax error at position 22 in 'OrderOptionalFields[0].Value eq 110'."
    }
  }
}
Optional Fields value store in Order Entity : 
[6:25 PM] Avijit Paul Poddar
"OrderOptionalFields": [
        {
"OrderUniquifier"301057,
"OptionalField""AECORDID",
"Value""110",
"OrderOptionalFieldType""Text",
"Length"60,
"Decimals"0,
"AllowBlank"false,
"Validate"false,
"ValueSet""Yes",
"TypedValueFieldIndex"21,
"TextValue""110",
"AmountValue"0.000,
"NumberValue"0,
"IntegerValue"0,
"YesNoValue"false,
"DateValue"null,
"TimeValue""1899-12-30T00:00:00Z",
"OptionalFieldDescription""AEC Web Order Id",
"ValueDescription""",
"UpdateOperation""Unspecified"
        }
      ]
Please help  me out how to do it?
