• What is the cause and solution for SAP error message LD220 - No unit of measurement has been maintained for execution times ?

  The SAP error message LD220 indicates that there is no unit of measurement (UoM) maintained for execution times in the context of logistics or production planning. This error typically arises when the system is trying to process data related to execution times, such as in production orders, routing, or work centers, but cannot find the necessary unit of measurement to interpret those times.
  Cause:
  
  Missing Unit of Measurement: The most common cause is that the unit of measurement for execution times has not been defined in the relevant master data (e.g., work center, routing, or production version).
  Incorrect Configuration: There may be a configuration issue in the system where the UoM settings are not properly aligned with the execution times.
  Data Inconsistency: There could be inconsistencies in the data where the execution times are defined but not linked to a valid UoM.
  
  Solution:
  To resolve the LD220 error, follow these steps:
  
  
  Check Work Center Configuration:
  
  Go to the work center configuration in SAP (Transaction code: CR01 or CR02).
  Ensure that the unit of measurement for execution times is maintained correctly. This is usually found in the "Basic Data" or "Capacity" tab.
  
  
  
  Review Routing:
  
  If the error occurs in the context of a routing, check the routing details (Transaction code: CA01 or CA02).
  Ensure that the execution times (setup, processing, teardown) have a valid unit of measurement assigned.
  
  
  
  Maintain Units of Measurement:
  
  If no UoM is defined, you can maintain it by going to the relevant master data and adding the appropriate UoM for execution times.
  Common units of measurement for execution times include hours (H), minutes (M), or seconds (S).
  
  
  
  Check Production Version:
  
  If applicable, check the production version settings to ensure that the execution times are correctly linked to a UoM.
  
  
  
  Data Consistency Check:
  
  Run consistency checks in the system to identify any other potential issues related to master data that might be causing the error.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or help resources for specific guidance on maintaining units of measurement in your version of SAP.
  
  
  
  Related Information:
  
  Transaction Codes: CR01 (Create Work Center), CR02 (Change Work Center), CA01 (Create Routing), CA02 (Change Routing).
  Units of Measurement: Ensure that the UoM used is compatible with the execution times defined in the system.
  SAP Notes: Check for any relevant SAP Notes that might address known issues or provide additional guidance on this error.
  
  By following these steps, you should be able to resolve the LD220 error and ensure that execution times are properly maintained with the appropriate units of measurement in your SAP system.
