• What is the cause and solution for SAP error message CFD_REGISTRY_CHECK350 - ABAP dictionary data type &1 is not supported for CDS View field &2 ?

  The SAP error message CFD_REGISTRY_CHECK350 indicates that there is an issue with the data type used in a Core Data Services (CDS) view. Specifically, it states that the ABAP dictionary data type specified is not supported for the field in the CDS view.
  Cause:
  This error typically arises due to one of the following reasons:
  
  Unsupported Data Type: The data type used in the ABAP Dictionary for the field in the CDS view is not compatible with the requirements of the CDS framework. Certain data types, such as complex types or those that are not scalar (e.g., structures, tables), cannot be used in CDS views.
  Incompatible Field Definitions: The field definitions in the CDS view may not align with the expected data types or structures defined in the ABAP Dictionary.
  Version Compatibility: The version of the SAP system may not support certain data types in CDS views, especially if you are using an older version of SAP.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Data Types: Review the data types used in the ABAP Dictionary for the fields in question. Ensure that they are scalar types supported by CDS views, such as:
  
  CHAR
  NUMC
  INT
  DEC
  STRING
  DATE
  TIMESTAMP
  
  
  
  Modify the CDS View: If the data type is not supported, consider modifying the CDS view to use a different field or to cast the data type to a supported type. You can use the CAST function in the CDS view to convert the data type if necessary.
  
  
  Check Field Definitions: Ensure that the field definitions in the CDS view are correctly defined and do not reference unsupported types. You may need to adjust the field definitions to align with the supported types.
  
  
  Update SAP System: If you are using an older version of SAP, consider updating to a more recent version that may have better support for various data types in CDS views.
  
  
  Consult Documentation: Refer to the official SAP documentation for Core Data Services to understand the supported data types and any limitations that may apply.
