There are a few mandatory fields that need to be filled in this template:
General: Language
General: Product Category ID
General: Base UoM

Error in backend: Processing canceled due to data inconsistency.

10. What is the maximum number of records for any given operation in Mass Data Maintenance?

Since the Mass Data Maintenance tool utilizes SOAP webservices to execute the update operations, it has the same constraints of the service interface in terms of timeout and amount of data that can be processed in a single request.

Based on this, the maximum number of records will vary by the business object being operated, as well as the amount of data being modified (for example, a file updating only an ID and a single text field will likely support more records than a file updating several text, numerical and ID fields).

For most operations, it is possible to take 5000 as the baseline for the maximum amount of records in a single Mass Data Maintenance run.
