• What is the cause and solution for SAP error message DB758 - Unable to select by initial value here ?

  The SAP error message DB758 "Unable to select by initial value here" typically occurs in the context of database operations, particularly when there is an issue with the selection criteria used in a database query. This error can arise in various scenarios, such as when using ABAP programs, reports, or during data extraction processes.
  Cause:
  
  Invalid Initial Value: The error often indicates that the program is trying to select data using an initial value (e.g., an empty string or null) that is not valid for the database field being queried.
  Data Type Mismatch: There may be a mismatch between the data types of the fields being queried and the values being used in the selection criteria.
  Incorrect Logic in Code: The logic in the ABAP code may not handle cases where initial values are present, leading to an attempt to perform a selection that is not valid.
  Database Constraints: There may be constraints or conditions in the database that prevent selection based on the provided criteria.
  
  Solution:
  
  Check Selection Criteria: Review the selection criteria in the ABAP code or report to ensure that it does not use initial values unless explicitly allowed. Ensure that the values being used for selection are valid and meaningful.
  Add Valid Default Values: If the selection criteria can potentially be empty, consider adding logic to provide default values or to skip the selection if the initial value is not valid.
  Debugging: Use the ABAP debugger to trace the execution of the program and identify where the initial value is being set or passed. This can help pinpoint the source of the issue.
  Review Data Types: Ensure that the data types of the fields being queried match the expected types in the database. If necessary, perform type conversions before executing the selection.
  Consult Documentation: Check SAP documentation or notes related to the specific transaction or program to see if there are known issues or additional guidance.
