• What is the cause and solution for SAP error message /IWBEP/CM_V4_MED164 - Precision not allowed on property '&1' of entity type '&2' ?

  The SAP error message /IWBEP/CM_V4_MED164 indicates that there is an issue with the precision of a property in an OData service. This error typically arises when the precision defined for a numeric property in the entity type is not allowed or is not compatible with the OData service's expectations.
  Cause:
  
  Precision Definition: The property in question has a precision defined in the data model that is not supported by the OData service. This can happen if the precision is set to a value that exceeds the limits allowed by the OData protocol.
  Data Type Mismatch: The data type of the property may not be compatible with the precision settings. For example, if a property is defined as a decimal with a specific precision, but the underlying database or OData service does not support that precision.
  Model Configuration: There may be issues in the way the entity type is configured in the OData model, leading to inconsistencies in how properties are defined.
  
  Solution:
  
  Check Property Definition: Review the definition of the property in the entity type. Ensure that the precision and scale are set correctly and are within the limits allowed by OData.
  Adjust Precision: If the precision is too high, consider reducing it to a value that is acceptable. For example, if the precision is set to 10, try reducing it to 5 or 6.
  Update OData Model: If changes are made to the property definition, ensure that the OData model is updated accordingly. This may involve regenerating the OData service or refreshing the metadata.
  Test the Service: After making changes, test the OData service to ensure that the error no longer occurs and that the service behaves as expected.
  
  Related Information:
  
  OData Specification: Familiarize yourself with the OData specification regarding data types and precision. This can help in understanding the limitations and requirements for defining properties in OData services.
  SAP Notes: Check for any relevant SAP Notes or documentation that may provide additional insights or updates related to this error message.
  Debugging Tools: Use SAP debugging tools to trace the execution and identify where the error is being triggered. This can provide more context on the issue.
  
  By addressing the precision settings and ensuring compatibility with the OData service, you should be able to resolve the error message /IWBEP/CM_V4_MED164.
