• Key Concepts: 
  A query is a request for data from a database. In the context of SAP, a query is a request for data from the Enterprise Service Framework Layer (BC-ESI-ESF). A query can be used to retrieve information from the database, such as customer records, product information, or financial data. 
  
  How to use it: 
  Queries can be used to retrieve data from the Enterprise Service Framework Layer. To create a query, you must first define the criteria for the query. This includes specifying which fields you want to retrieve and any conditions that must be met for the query to return results. Once the criteria is defined, you can execute the query and view the results. 
  
  Tips & Tricks: 
  When creating queries, it is important to ensure that the criteria is specific enough to return only relevant results. If the criteria is too broad, it may return too many results and make it difficult to find what you are looking for. Additionally, it is important to ensure that all conditions are properly specified so that only relevant results are returned.
