The current D365FO / D365SCM implementation allows the user to import data using the "Data Management" framework. For large amounts of data, the operation can be performed in batch and with multiple threads.

This is not possible with the 'Copy into Legal Entity' function, which allows the user to copy one or more entities from a master company to others in the same implementation. The current standard behavior for this application requires the copy to be performed in single-thread mode. The data is copied to the different legal entities one at a time.

To improve the solution, the following improvements are suggested:

1. Implement the "Retryable" batch framework (currently not implemented): with this solution, a batch in error (due to infrastructure communication problems, not data related) can be completed in any case, without any notable delay.
2. Create different threads, at least one per company, when the copy is executed in batch mode.
