• What is the cause and solution for SAP error message M!066 - You are using unit &1 and unit &2 in an info structure ?

  The SAP error message M!066 indicates that there is a conflict between the units of measure being used in an info structure. Specifically, it occurs when two different units of measure are being used in a way that is not compatible within the context of the info structure.
  Cause:
  The error typically arises in the following scenarios:
  
  Inconsistent Units: The info structure is trying to process data that uses different units of measure (e.g., pieces vs. kilograms) for the same key figures or characteristics.
  Configuration Issues: There may be a misconfiguration in the info structure settings or in the master data that leads to the use of incompatible units.
  Data Entry Errors: Incorrect data entry in the relevant transactions can lead to the use of different units of measure.
  
  Solution:
  To resolve the M!066 error, you can take the following steps:
  
  
  Check Info Structure Configuration:
  
  Go to the configuration of the info structure in the SAP system (transaction code SPRO).

  Review Master Data:
  
  Check the master data for the materials or objects involved. Ensure that the units of measure are consistent across all relevant records.
  Use transaction codes like MM03 (Display Material) to check the unit of measure settings for materials.
  
  
  
  Data Consistency:
  
  Ensure that the data being processed does not mix different units of measure. If necessary, convert the data to a common unit before processing.
  If you are using custom reports or queries, ensure that they are correctly handling units of measure.
