LB506 - Details

• The SAP error message LB506 indicates that there is a problem with the unit of measure (UoM) conversion in the context of inventory management or material management. Specifically, it means that the unit of measure you are trying to use (denoted as &1) is considered "superior" to the alternative unit of measure (denoted as &2). This typically occurs when the system is unable to convert between the two units of measure due to a configuration issue.
  
  Cause:
  
  Unit of Measure Configuration: The primary cause of this error is often related to the configuration of units of measure in the material master. The system expects a certain hierarchy or relationship between the units of measure, and if this is not correctly defined, the error will occur.
  Incorrect UoM Assignment: The unit of measure you are trying to use may not be correctly assigned as an alternative unit of measure for the material in question.
