1. Try to create a model from an SAP SuccessFactors Workforce Analytics import data connection.
2. Notice the error message.

• The OData API used for WFA access is not suitable for large data-extraction scenarios (like replicating WFA cubes).
• The OData API used to access WFA is designed for smaller data-consumption queries, to feed reports.
• This interface will abort when approaching 60-80K Cells per fetch. (Approx. 15-20 columns, by 4000 rows) 
• The behavior is by design. 

• Import different slices of data to fill the model, using the “Append” option in SAC.
• Edit the query filters for subsequent import jobs, by changing the restriction selections. (i.e. Import different 'slices' of data into the model sequentially, e.g. by Month, Org Unit, and Location)
