• What is the cause and solution for SAP error message WU182 - Plant group & cannot be deleted -> modules have been assigned ?

  The SAP error message WU182 indicates that a plant group cannot be deleted because there are modules (or other objects) assigned to it. This is a common issue when trying to maintain or clean up master data in SAP, particularly in the context of plant groups, which are used to categorize plants for various purposes, such as reporting or configuration.
  Cause:
  The primary cause of this error is that the plant group you are trying to delete is still in use. Specifically, it means that there are one or more modules (or other dependent objects) that are linked to the plant group, preventing its deletion. This could include:
  
  Production planning modules
  Material master records
  Purchasing documents
  Other configuration settings that reference the plant group
  
  Solution:
  To resolve this error, you need to identify and remove the dependencies associated with the plant group. Here are the steps you can take:
  
  
  Identify Dependencies:
  
  Use transaction codes like SE11 (Data Dictionary) or SE16 (Data Browser) to check for any tables that might reference the plant group.
  Common tables to check include:
  
  T001W (Plant Data)
  T001 (Company Codes)
  MARA (General Material Data)
  MARC (Plant Data for Material)
  
  
  You can also check for any configuration settings in the relevant modules (e.g., Production Planning, Materials Management) that might be using the plant group.
  
  
  
  Remove Assignments:
  
  Once you identify the dependent objects, you will need to either delete or reassign them to another plant group or category.
  For example, if there are materials assigned to the plant group, you may need to change their assignment to a different plant group.
  
  
  
  Delete the Plant Group:
  
  After ensuring that all dependencies have been removed, you can attempt to delete the plant group again using the appropriate transaction (e.g., OX17 for plant groups).
  
  
  
  Check for Custom Code:
  
  If there are custom developments or enhancements in your SAP system, ensure that they are not referencing the plant group in question.
