• What is the cause and solution for SAP error message ACMTOOL006 - When choosing "SELECT * FROM ", an Entity must be specified ?

  The SAP error message ACMTOOL006, which states "When choosing 'SELECT * FROM ', an Entity must be specified," typically occurs in the context of Core Data Services (CDS) views in SAP systems. This error indicates that the system expects a specific entity to be defined in the SELECT statement, but it is either missing or incorrectly specified.
  Cause:
  
  Missing Entity Name: The most common cause of this error is that the entity name is not provided in the SELECT statement. The syntax requires a valid CDS entity to be specified.
  Incorrect Syntax: There may be a syntax error in the SQL statement, such as missing quotes or incorrect formatting.
  Context Issues: The context in which the SELECT statement is executed may not have access to the specified CDS entity, or the entity may not be activated.
  
  Solution:
  
  
  Specify the Entity: Ensure that you are specifying a valid CDS entity in your SELECT statement. The correct syntax should look like this:
  SELECT * FROM <CDS-Entity>
  Replace <CDS-Entity> with the actual name of the CDS entity you want to query.
  
  
  Check Entity Activation: Make sure that the CDS entity you are trying to access is activated. You can check this in the ABAP Development Tools (ADT) or the relevant transaction in the SAP GUI.
  
  
  Review Syntax: Double-check the syntax of your SQL statement for any errors. Ensure that you are using the correct format and that there are no typos.
  
  
  Access Rights: Verify that you have the necessary permissions to access the specified CDS entity. If you do not have the required authorizations, you may need to contact your system administrator.
  
  
  Use the Correct Context: If you are executing the query in a specific context (like a particular package or application), ensure that the CDS entity is available in that context.
