We are working on building cubes in SSAS using GreenPlum as a source. We are using an OLE DB driver created for GreenPlum to pull the data. We are able to create the data source model and model the dimensions with no issues but when we go to process the dimensions we get the following error (Errors in the back-end database access module. Column -1 is too large for this instance of SQL Server 2014 Analysis Services.) and we are not able to find any solution for that error message on Google. Has anyone run into this error before and found a way to fix it? Thanks.
