There are tables for condition type ZCB0 but they cannot be maintained

Hi,

I'm encountering a problem with Conditions in SAP CRM 7.0 - TPM scenario.

Here you can find the error:

"A condition type was selected that cannot be maintained in this system or for which there are no maintanable tables in this system."

Procedure:

"If maintenance for condition records of a specific condition type/ table is required in this system, this must be set up in Customizing Notes for data transfer from the R/3 System"

Can anybdy better clarify what do I have to do?

Thanks in advance,

Andrea
