• What is the cause and solution for SAP error message QB123 - Blocks are not active because of the control key in material master ?

  The SAP error message QB123 indicates that the system is unable to activate the quality inspection (QI) blocks for a material due to the control key defined in the material master record. This typically occurs in the context of quality management (QM) processes within SAP.
  Cause:
  The error is caused by the control key assigned to the material in the material master record. The control key determines how the system handles quality management processes, including inspection lot creation and the activation of QI blocks. If the control key does not allow for the activation of QI blocks, the system will generate this error.
  Solution:
  To resolve the QB123 error, you can follow these steps:
  
  
  Check the Material Master Record:
  
  Go to the transaction code MM02 (Change Material) or MM03 (Display Material).
  Enter the material number and select the appropriate views (usually the Basic Data and Quality Management views).
  Check the control key assigned in the Quality Management view.
  
  
  
  Review the Control Key:
  
  The control key should be appropriate for the quality management processes you want to implement. Common control keys include:
  
  Q1: Quality inspection required
  Q2: Quality inspection not required
  
  
  If the control key is set to a value that does not allow for QI blocks, you may need to change it.
  
  
  
  Change the Control Key:
  
  If necessary, change the control key to one that allows for QI blocks. Make sure to consult with your quality management team or relevant stakeholders to determine the appropriate control key for your business processes.
  
  
  
  Save Changes:
  
  After making the necessary changes, save the material master record.
  
  
  
  Re-attempt the Process:
  
  After updating the control key, re-attempt the process that generated the error to see if the issue is resolved.
