Problen when I try to activate my message mapping

Question

Dears,
I have a problem when i try to active my message mapping. This mapping is already activated since 2012, but when i try to access in edit mode and I try to active (Without any change), returns fail.
Before press edit mode button:
Check: 
No errors found during object check
Test:
09:42:02 Start of test
Execution of mapping on server took 57 milliseconds Executed successfully
09:42:02 End of test
After press edit mode button (Witout any change):
Check:
Check Result for Object XXX
Source text of object Message Mapping: XXX| http://XXX has syntax errors:
Source code has syntax error:
Test:
09:44:46 Start of test
Source text of object Message Mapping: MM2SUSOrderCreate | http://sap.com/xi/SRM/SupplierEnablement/Global has syntax errors:
Source code has syntax error:
09:44:48 End of test
why does this happen?
Regards

Hi Jannus,
Thanks for your response.
I have analyzed the scenario and I find errors in my java functions when check mapping step by step with "Display Queue" (Function tag in MM).
This functions was ok when we had XI, but now with PI, It returns error.
There is any change after the upgrade to pi with respect to java methods or in relation to java mapping?

I haven't seen your answer. My basis team import content version in PI, Is it neccesary doing the same in SRM?
