• What is the cause and solution for SAP error message WY028 - No materials selected for sub-range & ?

  SAP Error Message:
  
  WY028 - No materials selected for sub-range &
  
  Cause:
  This error occurs in SAP Retail (usually in the assortment or merchandise planning modules) when the system expects materials to be assigned or selected for a particular sub-range (a subset of a product range), but none have been selected or assigned. The placeholder "&" in the message is replaced by the sub-range identifier.
  In other words, the system is trying to process or generate data for a sub-range, but it finds that no materials are linked to that sub-range, which is mandatory for the process.
  
  When does it occur?
  
  During assortment planning or assortment assignment.
  When generating reports or planning data that require materials to be assigned to sub-ranges.
  When creating or maintaining sub-ranges without assigning any materials.
  During merchandise hierarchy or range maintenance if sub-ranges are defined but empty.
  
  
  Solution:
  
  
  Assign Materials to the Sub-Range:
  
  Go to the transaction or application where sub-ranges are maintained (e.g., Assortment Planning, Merchandise Planning).
  Identify the sub-range mentioned in the error.
  Assign the relevant materials to this sub-range.
  Save the changes.
  
  
  
  Check Material Master and Range Assignments:
  
  Verify that the materials intended for the sub-range are correctly maintained in the material master.
  Ensure that the materials are assigned to the correct merchandise hierarchy and sub-range.
  
  
  
  Validate Sub-Range Setup:
  
  If the sub-range is not supposed to have materials (e.g., it was created by mistake), consider deleting or deactivating the sub-range.
  Alternatively, if the sub-range is new, ensure that materials are assigned before running processes that require them.
  
  
  
  Re-run the Process:
  
  After assigning materials, re-execute the process or report that triggered the error.

  Sub-ranges are part of the merchandise hierarchy and assortment structure. Proper configuration and data maintenance are critical.
  
  
  
  Best Practices:
  
  Regularly review sub-range assignments.
  Ensure that all sub-ranges used in planning or reporting have at least one material assigned.
  Use reports or queries to identify empty sub-ranges.
