Call from MII using HTTPPost to standard ME WebService - no data returned.

[former_member202208]

Hi experts,

I am making a HttpPost Call to Standard SAP ME webservice from MII transaction to create a PO, in the PostData we are setting the SOAPxml request.

If there is error in creating a PO, MII transaction doest show me the response data, In the response, i see the following trace.

• [WARN] [HTTP_Post_0] Skipping execution of output links due to action failure.
• [ERROR] Uncaught exception from HTTP_Post_0, 

data set to HttpPost request.

Trying to retrieve the ME response from HTTP_Post_0.ReturnAsString & HTTP_Post_0.ReturnAsXML methods.

am i missing something?

If you are using MII 12.2 you can add a Catch block and then examine the error message from the Catch branch with a Trace action.

Thanks Steve,

I see "13:51:43.351 [DEBUG] HTTP Post:false statusText:Internal Server Error statusCode:500

" message.

When i pass the correct data, i see "13:49:10.633 [DEBUG] HTTP Post:true statusText:OK statusCode:200" message and there is no error.

Why could this be happening.? If the input data is incorrect, i should get an error message from the server/app and it should not stop the flow.

am i missing something?

Thanks,

Sorry for the double post [extra post removed by moderator ;-)];

According to help document;

You can link the following parameters to this action:

Parameter	Description	Type
DisableHandling	User-defined message	Boolean
Source	The action that is throwing the exception	String
ActionType	Type of the action that is throwing the exception	String
Message	Message the exception contains	String
ExceptionType	Type of exception thrown	String
ExceptionCaught	If an exception occurred, the value is true	Boolean
Succeeded	Value is always true	Boolean

I dont see any of these in link editor for catch block.

I am using MII 12.2.2.235.

Add a Sequence step after the Catch block, you will get two branched sequences.  Add a Tracer action to the "caught" branch (red connector) and map the Message property there.

Just curious, why are you using HTTPPost instead of Webservice action to call the web service?

Thanks Steve.

With catch block i could see the response coming back from ME.

I observed that, when i use the Webservice call, it expects me to fill/map in all the data elements value. but if i use http call, i can send the minimal xml elments in the SOAP call and it works.

Thanks..

You can actually use Webservice action block but you have to create 3 sequence steps to modify the request to remove the non-required nodes, WS1 without execution, Assignment action (to remove the un-needed nodes from WS1 request and assign the rest of the request required values), WS2 and assign its request from the modified WS1 request, and execute WS2

Thanks Steve,

I will try that option aswell.

I have one more question:

I am trying to set the HTTPPost ReturnXML (which is a SOAP response xml) to a Transaction parameter of type xml, from which i plan to use to retrive the data or faultcode or faultstring etc..

I have a Transaction output param of type xml (ReturnData). In the POGrid (iGrid), the ReturnData wont show up under the 'Column names' for POXacQuery (Querytemplate). If i change the datatype of ReturnData to String, it shows up and i can see the data in Applet.

I need to the response so that we can display proper message.

Is it that we cant use a Transaction parameter of type xml to assign SOAP return xml or does it expect the return xml data in a specific format.??

Pls advise.

Thanks,

PS: I am new to MII.

Not sure about the issue with the HTTPPost response.  I have only used Webservice Action Block for ME Webservice requests, and not had any issues with the response xml assignments.

Steve,

Thanks. With Webservice action, I am passing/setting minimal xml elments in the SOAP call and it works.

but, the repose has only one root node and no details on the PO created.

<ns2:ProductionOrderCreateConfirmation_sync xmlns:ns2="http://sap.com/xi/ME" xmlns="http://sap.com/xi/SAPGlobal/GDT"/>

any suggestion?

Which version/build of SAPME are you using?

- Steve

[former_member202208]

Its;

Base 6.0.2.2 Counter 12

Build ID 138945

[former_member196557]

I thint at this point you will need to log a ticket to get this resolved.  The WSDL for 6.0.3 Counter 24 for ProductionOrderService appears to contain the elements for a valid response; I don't have access to a 6.0.2 system to compare with.

Hi,

ME Base 6.0.2.6 Counter 10
