• What is the cause and solution for SAP error message /SCMB/MC_PB304 - Material &1: no weight defined ?

  The SAP error message /SCMB/MC_PB304 Material &1: no weight defined typically occurs in the context of SAP Supply Chain Management (SCM) when a material does not have a weight defined in the system. This can affect various processes, such as transportation planning, inventory management, and logistics execution.
  Cause:
  
  Missing Weight Data: The primary cause of this error is that the material master record for the specified material does not have a weight defined. This can happen if the material was created without entering weight information or if the weight data was inadvertently deleted or not updated.
  Incorrect Material Type: Sometimes, the material type may not require weight information, leading to confusion when the system expects it.
  Configuration Issues: There may be configuration settings in the SCM module that require weight data for certain processes, and if the material does not comply, this error can occur.
  
  Solution:
  
  
  Update Material Master:
  
  Go to the Material Master (Transaction Code: MM02).
  Enter the material number that is causing the error.
  Navigate to the relevant views (usually Basic Data 1 or Basic Data 2) and ensure that the weight is defined in the appropriate fields (e.g., Gross Weight, Net Weight).
  Save the changes.
  
  
  
  Check Material Type Settings:
  
  Ensure that the material type allows for weight data to be entered. If necessary, consult with your SAP configuration team to verify that the material type settings are appropriate.
  
  
  
  Review Configuration:
  
  If the issue persists, review the configuration settings in the SCM module to ensure that weight data is required only for materials that need it. This may involve checking the settings in the relevant customizing transactions.
  
  
  
  Testing:
  
  After updating the material master, test the process that triggered the error to ensure that the issue is resolved.
