Beas WEB Server is a single process. Transactions in SAP B1 take time. While the transaction is running, the WEB Server cannot work on other requests.

Concept: The Beas WEB Server returns only a request id and send the POST command to the Beas documentation - common service . This does not take time and the Beas WEB Service can answer next requests. The WEB client can use the RequestAnswerService to ask if the transaction is executed and can delete the request with DEL RequestAnswerService.

 

With asynch=true the system sends the command to the Beas common service and returns only the request number on which you can read the answer.

In this way you will not stop the Web server for working on time-intensive commands.

 

Example

 

Create Work order over Common service:

 

POST odata4/WorkOrder?async=true

 

Body

{"WorkorderPos":[{"ItemCode":"FP","Quantity":2}]}

 

This return

{

  "TransactionID": 5726

}

 

Now you can request the result

This can take longer time. Please ask max. 1 time / 3 seconds.

 

RequestAnswerService?$filter=RequestId eq "5726"

 

This returns empty value, if (for example) this type of string does not exist:

 

{

  "value": [

       {

          "RequestNumber": 478,

          "RequestId": "5726",

          "SessionId": "mah-de-desktop2828",

          "AnswerType": 0,

          "AnswerText": "6002207",

          "PARAMETER1": "",

          "StationId": "mah-de-desktop",

          "Closed": false,

          "EntryDate": "2021-03-25T10:51Z"

       }

   ]

}

 

 

At the end you must close the answer (note: you must send the parameter as String array)

RequestAnswerService/Close(["5726"])
