• What is the cause and solution for SAP error message WPLG001 - You need to specify either the category or the assortment ?

  SAP Error Message:
  
  WPLG001: You need to specify either the category or the assortment
  
  Cause:
  This error occurs in SAP Retail (often in the context of assortment planning, assortment management, or assortment assignment processes) when the system expects either a Category or an Assortment to be specified, but neither has been provided.
  
  The system requires at least one of these two parameters to proceed with the operation (e.g., when creating or maintaining assortments, or when running reports or planning functions related to assortments).
  If both fields are left blank, the system cannot determine the scope or context of the operation, hence it throws this error.
  
  
  Solution:
  To resolve the error WPLG001, you need to:
  
  
  Specify a Category or an Assortment:
  
  Enter a valid Category (e.g., product category or merchandise category).
  Or enter a valid Assortment (a predefined group of products or categories).
  
  
  
  Check the Input Screen or Selection Criteria:
  
  Make sure that at least one of these fields is filled before executing the transaction or report.
  
  
  
  Verify Master Data:
  
  Ensure that the categories and assortments you are trying to use exist and are correctly maintained in the system.
  
  
  
  If unsure which to use:
  
  Consult your business process or functional consultant to understand whether the process requires a category or an assortment.
  Sometimes, depending on the transaction, one might be mandatory and the other optional.
  
  
  
  
  Related Information:
  
  Assortment: A collection of products or categories grouped for planning, ordering, or reporting purposes.
  Category: A classification of products, often hierarchical, used to organize merchandise.
  This error is common in modules like SAP Retail Assortment Planning (WPLG) or Assortment Management.
  The error message is a validation check to ensure meaningful input for assortment-related processes.
  If you are working with custom reports or Z-programs, check the selection screen logic to ensure that either category or assortment is mandatory.
  
  
  Example Scenario:
  
  You are trying to run an assortment report or create an assortment assignment.
  The selection screen asks for either a category or an assortment.
  You leave both fields blank and execute.
  The system returns WPLG001 because it needs at least one to filter the data.
  
  
  If you continue to face issues, check SAP Notes or consult your SAP Retail functional consultant for further assistance.
