This activity is used when there are two or more part service contract lines in the customer’s part service contract for the same service type. In this case, no part service contract ID and part service line number are retrieved to the service type line. You have to select the part service contract and the part service contract line that are valid for the specified service type, before saving the service type line.
A specific part service contract ID and a part service contract line number is now valid for the service type.
