  SAP Error Message:
  WXPO003 - Merch. category missing in function module 'ARTICLE_GET_FOR_HIERARCHY'
  
  Cause:
  This error occurs because the function module ARTICLE_GET_FOR_HIERARCHY expects a merchandise category (Merch. category) to be provided as input or to be available in the context, but it is missing or not maintained for the article or hierarchy node being processed.
  
  The merchandise category is a key classification attribute used in Retail and Merchandise Management (IS-Retail).
  If the merchandise category is not assigned to the article or the hierarchy node, the function module cannot proceed and throws this error.
  This often happens during article master data retrieval or hierarchy processing when the system tries to determine the merchandise category but finds it empty.
  
  
  Solution:
  
  
  Check Merchandise Category Assignment:
  
  Verify that the article has a merchandise category assigned in the article master.
  Use transaction MM42 (Change Article) or MM41 (Display Article) to check the merchandise category field.
  If missing, assign the correct merchandise category.
  
  
  
  Check Hierarchy Node Settings:
  
  If the function module is called with a hierarchy node, ensure that the node has a merchandise category assigned.
  Use transaction WHS1 or the relevant hierarchy maintenance transaction to check and maintain the merchandise category.
  
  
  
  Data Consistency:
  
  Run consistency checks on article master data and hierarchy data to ensure no missing or inconsistent merchandise category assignments.
  
  
  
  Debugging:
  
  If the error persists, debug the function module ARTICLE_GET_FOR_HIERARCHY to see where the merchandise category is expected and why it is missing.
  Check the input parameters and the data retrieval logic.
  
  
  
  Transport and Customizing:
  
  Ensure that the merchandise category customizing is correctly transported and available in the system.
  Check IMG settings under Retail ? Master Data ? Article ? Merchandise Category.
