CAD attachment, xml empty

Hi Gurus,

Regarding the CTI,

My requirement, to read the call history (i.e. please pres 1 to payment section, press 2 to change the address, press 3 to pay with a debit card, press 4 billing information.. etc ) and show all this history within in the webclient.

I am able to receive the call, but when I try to get this history information, I cannot reach it.

What I did was set a breakpoint within

GET_CAD(CL_CRMCMP_B_CUCOBUPA_IMPL)

and variable ev_transfer is comming empty.

I've checked and I've this customizing

and

my attribute is configured in my Z profile

Does anybody know if this is the proper way to get the CAD xml data to get call history.

Any help is useful.

Thanks in advance

Regards, Diego
