Validating multiple Datamappers

We were facing these strange error during ADM import on target system:

Source component % does not exist.(SBL-EAI-04063)

This was coming when we tried to import the datamappers inot target system.We follow a continous deveopment model with numerous integrations, and the external IOs for them keep on changing. The problem occurred because the new WSDL imported did not contain some IC levels which were developed and mapped earlier. But the problem was complicated because now we did not know which datamapper to check.

Now there is a very useful button which could help us here. On the Datamap administration view, there is a validate button on the top applet. It checks the structure of the mapped IOs with the ones compiled into the SRF and threw up validation errors. For some time now I have been wondering the functionality behind this button.
I found this in the Siebel log files when the button was clicked:

Begin: Business Service 'EAI Data Transformation Engine' invoke method: 'Validate'

But if you check the definition of this BS in tools, you will not fin the Validate method. But after a little more tweaking, I was able to figure out the input parameters. One thing I found was that if the Datamap is valid, the BS does not return or throw any message, and if there is any validation error, it throws an exception. Hence if multiple datamps need to be validated, the try catch loop must be put inside a loop. I wrote a simple script at client side services which validates multiple datamaps in one go. The search spec can be modified according to your project requirements.

function Service_PreInvokeMethod (MethodName, Inputs, Outputs)
var oBCDataMap = "";
var sMessage= "";
var iCount = 0;
oBCDataMap = TheApplication().GetBusObject("EAI Data Map").GetBusComp("EAI Object Map");
oBCDataMap.SetSearchSpec("Source Object Name","*");
var oBSDTE = TheApplication().GetService("EAI Data Transformation Engine");
var psInput = TheApplication().NewPropertySet();
var psOutput = TheApplication().NewPropertySet();
var bIsRecord = oBCDataMap.FirstRecord()
sMessage = sMessage + oBCDataMap.GetFieldValue("Name") + ":" +e.toString() + "\r";
iCount = iCount + 1;
bIsRecord = oBCDataMap.NextRecord();

sMessage == "" ? TheApplication().RaiseErrorText(iCount + " Datamaps validated successfully.") : TheApplication().RaiseErrorText(sMessage);
return (CancelOperation);

When the code is execute, it validates all Datamaps using the EAI Data Transformation Engine BS's Validate method, and presents the errors in a message box.

You can hit Ctrl-C now to copy this message, and paste this in notepad.
AMSRefData_ServiceCenter:Parent component map 'q' not found.(SBL-EAI-04061)
AMSRefData_Service_Func:Parent component map 'q' not found.(SBL-EAI-04061)
What'ya think ?
