• What is the cause and solution for SAP error message MC765 - Field specification with * and - only allowed for DB views ?

  The SAP error message MC765, which states "Field specification with * and - only allowed for DB views," typically occurs in the context of data extraction or reporting when you are trying to use a field specification that is not valid for the type of data source you are working with. This error is often encountered in the context of SAP's data extraction tools, such as InfoSets or queries.
  Cause:
  The error is triggered when you attempt to use a wildcard character (* or -) in a field specification for a data source that does not support it. Specifically, this is common when you are working with database views (DB views) or other types of data sources that have strict field selection criteria.
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check the Data Source: Ensure that you are using a database view or another appropriate data source that allows for wildcard specifications. If you are using a different type of data source (like a table or a structure), you may need to adjust your approach.
  
  
  Modify Field Specifications: Instead of using * (which selects all fields) or - (which may be used to exclude fields), specify the exact fields you want to include in your query or report. This means listing out the field names explicitly.
  
  
  Review Query/InfoSet Design: If you are using an InfoSet or a query, review the design to ensure that it adheres to the requirements of the data source. Make sure that the fields you are trying to select are compatible with the data source.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for guidance on the specific data source you are using. This can provide insights into the limitations and requirements for field specifications.
  
  
  Testing: After making changes, test the query or report again to ensure that the error is resolved.
