3168763 - "Columns cannot be matched!" while linking Date Dimensions in SAP Analytics Cloud (SAC)

Symptom

  • "Columns cannot be matched!" while linking Date Dimensions in SAP Analytics Cloud (SAC).
  • Browser-Based Data blending between Live Model (based on SAP BW) and Import/Acquired Model.

Environment

  • SAP Analytics Cloud (Enterprise)
  • SAP Business Warehouse
  • SAP BW/4HANA
  • S/4HANA

Reproducing the Issue

  1. Login to SAC.
  2. Create an Import/Acquired Model based e.g. on CSV file where Date Dimension is defined.
  3. Create a Live Model base on BW direct connection where Date Dimension has DataType = DATS.
  4. Create a Story.
  5. Try to create Linked Dimensions between the Date Dimensions => error message: "Columns cannot be matched!"

Cause

  • Product limitation.
  • BW/S4 Live Model and Acquired Model on Date Dimension is not supported since Data type mismatch.
  • For more details, please see SAP Wiki: SAP Analytics Cloud Support Matrix

=> topic Link Models (aka 'Blending'. Multiple data sources within a single visualisation):

"D) Blending of date dimensions with BW is currently not supported."
