PI 7.31 IDOC Packaging Message Mapping Error

[former_member138523]

Hi PI Experts,

Scenario : IDOC to Files(3 files using Multi Mapping) using ISOC Packaging.

Configured End to end during testing I am getting the following Error at Mapping Step.

Error : Mapping "http://BB/PTP/I_QTP_167/PurchaseOrder/OM_ORDERS_ORDERS06_to_TPMPurchaseOrderProcessing_Async_In" failed to execute: MappingException: Mapping failed, ClassCastException: class com.sap.aii.af.service.cpa.impl.object.ParamMappingCPAObjectImpl:service:com.sap.aii.af.cpa.svc@com.sap.engine.boot.loader.

ResourceMultiParentClassLoader@21471a6b@alive incompatible with interface com.sap.aii.af.service.cpa.ESRParamMappingCPAObject:service:com.sap.aii.af.cpa.svc@com.sap.engine.boot.loader.ResourceMultiParentClassLoader

Transmitting the message to endpoint <local> using connection IDoc_AAE_http://sap.com/xi/XI/System failed, due to: com.sap.aii.af.service.mapping.MappingException: Mapping failed.

I Tested the payload in Message Mapping, working fine.

Note : I am using RFC look up in MM to fectch values from ECC System.

Thanks in Advance.

Hi Kumar,

Check if rfc lookup parameters binding has been done.

Please re-do it and then test.

Sadly it doesn't work for me.I've rebuild the Operation mapping and tested it through runtime (including correct RFC lookup parameters), but it doesn't change the returned error.

Hi,

If it is working in Message  mapping and operation mapping, it should work in run time as well.

Did you checked the run time payload?

Go to moni and check the run time payload and see what's wrong with the live data.

Koen,

Try refreshing the cache, and if you are using any Runtime UDF/functions, try checking their references again.

If this does not help you, I would suggest to check the system services (NWA cache services).

Hi,

Can you check if

1.) If our operation map and message map is having the same occurence.

2.) In the message mapping all the messages are getting generated properly.

Hi Abhishek,

Thanks for the help,

1.) Yes is has (1 to 0...unbounded)

2.) In the testtab they are, but not in runtime

As a last option please try to re-create the operation maps and the message maps from scratch, please do not try and copy the existing maps into new ones.

One advantage to this is it would eliminate any redundant mapping or references which could have happened previously.

Hope this helps!
