• What is the cause and solution for SAP error message SPRX354 - Main object of an inline type. Inline type first have to be converted. ?

  The SAP error message SPRX354 indicates that there is an issue with the use of inline types in your ABAP code. Specifically, it suggests that you are trying to use an inline type without first converting it to a main object type. This typically occurs when you are working with inline declarations and trying to use them in a context where a main object type is expected.
  Cause:
  The error arises when:
  
  You are trying to use an inline type (like a structure or a table type defined inline) in a context that requires a more concrete type.
  The inline type has not been converted to a main object type, which is necessary for certain operations or method calls.
  
  Solution:
  To resolve this error, you need to ensure that you convert the inline type to a main object type before using it in the context that requires it. Here are some steps you can take:
  
  
  Define a Main Object Type: Instead of using an inline type directly, define a structure or table type in the Data Dictionary (SE11) or as a global type in your ABAP program.
  
  
  Use Type Casting: If you need to use an inline type, you can cast it to a main object type. For example, if you have an inline structure, you can create a variable of the main structure type and assign the inline structure to it.
  
  
  Check Context: Review the context in which you are using the inline type. Ensure that it is appropriate for the operation you are trying to perform.
  
  
  Refactor Code: If possible, refactor your code to avoid using inline types in situations where main object types are required.
  
  
  Example:
  Here’s a simple example to illustrate the concept:
  DATA: lv_value TYPE i,
        lt_table TYPE TABLE OF string.
  
  " Inline declaration
  DATA(lo_inline) = VALUE #( ( 'Value1' ) ( 'Value2' ) ).
  
  " This will cause SPRX354 error
  " lt_table = lo_inline.
  
  " Correct approach
  DATA: lt_main_table TYPE TABLE OF string.
  lt_main_table = lo_inline.
  Related Information:
  
  ABAP Inline Types: Inline types are a feature in ABAP that allows you to define types directly in the code without needing to declare them in the Data Dictionary.
  Type Conversion: Understanding how to convert between inline types and main object types is crucial for effective ABAP programming.
  SAP Documentation: Refer to the official SAP documentation for more details on inline types and type conversion in ABAP.
  
  By following these guidelines, you should be able to resolve the SPRX354 error and improve your ABAP code's type handling.
