Error when i create a BP - Person in IC Web CLient

Hi,

In Our Business Process: When call comes to Contact center, the agent can create a new customer (Person and Organization) in through ICWeb client.

We configurated our account identification profile assigning  z grouping to  z default role in the account creation and Role BUP001 for creation of contact person.

When we create a organization in IC WebClient  is created correctly  but when you want to create a Person, the systems shows a dump

"Source type \CLASS=CL_CRM_BOL_ENTITY is not compatible, for the purposes of assignment, with target type \CLASS=CL_BSP_WD_VALUE_NODE"

Doing this also i am not able to create new customer person.

Does anybody know about how can i resolve this problem?

Regards

Laura
