• What is the cause and solution for SAP error message ST_BUILDER_MESSAGES019 - No reference to deep object allowed ?

  The SAP error message ST_BUILDER_MESSAGES019 ("No reference to deep object allowed") typically occurs in the context of SAP's ABAP programming environment, particularly when dealing with deep structures or complex data types. This error indicates that there is an attempt to reference a deep object (like a nested structure or table) in a way that is not permitted.
  Cause:
  
  Deep Structures: The error often arises when you are trying to create a reference to a deep structure or a nested table in a way that is not allowed by the ABAP language rules.
  Data Declaration Issues: It may occur if you are trying to use a deep structure in a context where only flat structures or simple data types are allowed.
  Incorrect Use of References: Attempting to use a reference to a deep object in a context that does not support it, such as in certain function calls or method parameters.
  
  Solution:
  
  Check Data Types: Ensure that you are not trying to pass a deep structure where a flat structure is expected. If necessary, create a flat version of the data structure to use in the context that is causing the error.
  Use Proper References: If you need to work with deep structures, ensure that you are using the correct syntax and methods to reference them. For example, use the REF TO syntax appropriately.
  Review Function Modules/Methods: If the error occurs when calling a function module or method, check the parameter definitions to ensure that they accept deep structures if you are trying to pass one.
  Debugging: Use the ABAP debugger to trace where the error occurs and inspect the data types being used at that point in the code.

  ABAP Documentation: Refer to the official SAP ABAP documentation for guidelines on working with data types, especially deep structures and references.
