one

Explanation
 A TP called the CPI-C Set_Deallocate_Type service
to set the deallocate type characteristic for a conversation. The
deallocate_type parameter specified a value of CM_Deallocate_Confirm,
which is not compatible with the established conversation sync_level
of CM_none.

System action
 The system returns a program_parameter_check
(decimal 24) return code to the caller of the Set_Deallocate_Type
service.

Programmer response
 Do one of the following:  See the description of the CPI-C Set_Deallocate_Type service in
the CPI-C Reference for explanations of valid values
for the Deallocate_type parameter. Specify a value other than CM_Deallocate_Confirm
on the deallocate_type parameter.
See the description of the CPI-C Set_Sync_Level service in the CPI-C
Reference for explanations of valid values for the sync_level
parameter. Specify a value other than CM_none on the sync_level parameter.
