  Error Message
  W8112 - Specify a reference for expression &
  
  Cause
  This warning message typically occurs in the ABAP runtime environment or during program execution when an expression (usually a variable or field) is used without a proper reference context. In other words, the system expects a fully qualified reference to a data object, but only a partial or ambiguous expression is provided.
  Common scenarios include:
  
  Using a field or variable in an expression where the system cannot determine the exact data object because the reference is missing or incomplete.
  Accessing components of a structure or table without specifying the full path.
  Using expressions in dynamic programming or field-symbols where the reference is unclear.
  
  
  Explanation
  SAP requires that expressions, especially those involving complex data types (structures, internal tables, objects), be fully qualified to avoid ambiguity. For example, if you have a structure ls_data with a component field1, you should refer to it as ls_data-field1 rather than just field1.
  If the system encounters an expression without a clear reference, it raises this warning to prompt the developer to specify the reference explicitly.
  
  Solution
  
  Specify the full reference path for the expression. For example, instead of using just field1, use ls_data-field1 or itab[index]-field1.
  Check the context where the expression is used and ensure that the variable or field is properly declared and referenced.
  If using field-symbols or data references, ensure they are assigned correctly before use.
  In dynamic programming scenarios (e.g., using ASSIGN or GET REFERENCE), verify that the reference is valid and assigned before the expression is evaluated.
  Review the code to avoid ambiguous or incomplete references.
  
  
  Example
  Incorrect:
  WRITE: field1.
  If field1 is a component of a structure or internal table, this will cause the warning.
  Correct:
  WRITE: ls_data-field1.
  
  Related Information
  
  Check SAP Note or documentation related to ABAP runtime errors and warnings.
  Review ABAP programming guidelines on data referencing and field access.
  Use debugging tools to trace where the ambiguous expression is used.
  This warning does not usually stop program execution but should be corrected to avoid unexpected behavior.
