• What is the cause and solution for SAP error message SADL_CONDITION011 - Parser was unable to reduce stack to a single element ?

  The SAP error message SADL_CONDITION011 ("Parser was unable to reduce stack to a single element") typically occurs in the context of the SAP ABAP programming environment, particularly when using the SAP ABAP Data Layer (SADL) for handling queries and conditions.
  Cause:
  This error generally indicates that there is an issue with the way conditions are defined in a query. The parser is unable to interpret the conditions correctly, leading to a situation where it cannot reduce the stack of conditions to a single element. This can happen due to:
  
  Complex Conditions: The conditions defined in the query may be too complex or improperly structured.
  Syntax Errors: There may be syntax errors in the way conditions are written.
  Incompatible Data Types: The conditions may involve incompatible data types or fields that cannot be compared.
  Logical Errors: There may be logical inconsistencies in the conditions that make it impossible for the parser to resolve them.
  
  Solution:
  To resolve the SADL_CONDITION011 error, you can take the following steps:
  
  Review Conditions: Check the conditions defined in your query. Simplify them if possible and ensure they are logically consistent.
  Check Syntax: Ensure that the syntax used in the conditions is correct. Look for any typos or incorrect operators.
  Data Types: Verify that the fields being compared in the conditions are of compatible data types. If necessary, perform type conversions.
  Debugging: Use debugging tools to step through the code and identify where the parser fails. This can provide insights into which specific condition is causing the issue.
  Documentation: Refer to SAP documentation or community forums for guidance on how to structure conditions correctly in SADL.
  Test Incrementally: If you have multiple conditions, try testing them incrementally. Start with a simple condition and gradually add more complexity to identify the problematic part.
