Contract Mass Change - Enhancement error

Hi all

We're implementing SRM 7.02 EC

We have implemeted BadI /SAPSRM/CTR_MC_BADI and created new change method (added new entry in Table BBPV_CTR_MASSOP) in order to add a custom View for custom parameters.

We have followed the steps detailed in SAP Help:

http://help.sap.com/saphelp_srm701/helpdata/en/8d/3a9442bf2d1031e10000000a1550b0/content.htm

And we are having the same errors as these ones:

http://scn.sap.com/thread/3308666

We have configured the view as a plug and everything, but it keeps giving dumps.

ERROR: Controller MAIN Does Not Exist (termination: RABAX_STATE)

Any ideas are welcome.

Thanks
