• What is the cause and solution for SAP error message QP501 - Sample unit &1 is not compatible with task list unit of measure & ?

  The SAP error message QP501 indicates that there is a mismatch between the unit of measure (UoM) of a sample unit and the unit of measure defined in the task list for a quality inspection. This typically occurs in the context of quality management (QM) processes, particularly when dealing with inspection lots and sample management.
  
  Cause:
  
  Unit of Measure Mismatch: The sample unit defined in the inspection lot does not match the unit of measure specified in the task list. For example, if the task list is set to use "pieces" but the sample unit is defined as "kilograms," this error will occur.
  
  Configuration Issues: There may be issues in the configuration of the quality management module, particularly in how units of measure are defined and linked to task lists and inspection plans.
  Data Entry Errors: Incorrect data entry when creating the inspection lot or task list can lead to this mismatch.
  
  
  Solution:
  
  Check Task List
