• What is the cause and solution for SAP error message LCM_COMMON189 - CDS View source is mandatory ?

  The SAP error message LCM_COMMON189 indicates that a CDS (Core Data Services) view source is mandatory but has not been specified. This error typically arises in the context of SAP applications that utilize CDS views for data modeling and reporting.
  Cause:
  The error occurs when you are trying to create or modify a CDS view, and the system requires a source definition (like a database table or another CDS view) to be specified, but it has not been provided. This can happen in various scenarios, such as:
  
  When defining a new CDS view and forgetting to specify the source.
  When modifying an existing CDS view and inadvertently removing or not specifying the source.
  When using a tool or transaction that requires a CDS view to have a defined source.
  
  Solution:
  To resolve the error, you need to ensure that a valid source is specified for the CDS view. Here are the steps you can take:
  
  
  Check the CDS View Definition:
  
  Open the CDS view in the ABAP Development Tools (ADT) or the relevant transaction.
  Ensure that the @AbapCatalog.sqlViewName annotation is present and that the source table or view is correctly defined in the FROM clause.
  
  
  
  Specify the Source:
  
  If the source is missing, add the appropriate database table or another CDS view in the FROM clause of your CDS view definition.
  Example:
  define view Z_MY_CDS_VIEW as select from my_table
  {
    key field1,
    field2,
    field3
  }
  
  
  
  
  Activate the CDS View:
  
  After making the necessary changes, activate the CDS view to ensure that the changes take effect.
  
  
  
  Check for Dependencies:
  
  If your CDS view depends on other views or tables, ensure that those are also correctly defined and activated.
