  The SAP error message CFD_REGISTRY_CHECK148 indicates that there is a conflict in the Common Data Services (CDS) registry due to the use of the same union suffix in multiple CDS views or entities. This typically occurs when two or more CDS views are defined with the same union suffix, which can lead to ambiguity in the data model.
  Cause:
  The error is caused by:
  
  Multiple CDS views or entities using the same union suffix, which is not allowed as it can create confusion in the data model.
  The union suffix is intended to uniquely identify a union of data sources, and having duplicates can lead to issues in data retrieval and processing.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Identify Conflicting CDS Views:
  
  Check the CDS views or entities that are registered in the CDS registry. Look for the ones that are using the same union suffix.
  You can use transaction codes like SE11 (Data Dictionary) or SE80 (Object Navigator) to find the definitions of the CDS views.
  
  
  
  Rename the Union Suffix:
  
  Modify the union suffix of one or more of the conflicting CDS views to ensure that each has a unique suffix.
  This can be done by editing the CDS view definition in the ABAP Development Tools (ADT) or in the relevant transaction.
  
  
  
  Activate the Changes:
  
  After making the necessary changes, activate the modified CDS views to ensure that the changes take effect.
  
  
  
  Test the Changes:
  
  After activation, test the CDS views to ensure that they are functioning correctly and that the error message no longer appears.
