• What is the cause and solution for SAP error message 28549 - Error in compilation of dependency &1: Type required in line &2 ?

  The SAP error message 28549, "Error in compilation of dependency &1: Type required in line &2," typically occurs during the activation or compilation of ABAP programs, function modules, or classes. This error indicates that there is a missing type declaration in the specified line of code, which prevents the ABAP runtime from properly compiling the program.
  Cause:
  
  Missing Type Declaration: The most common cause is that a variable or data object is being used without a proper type declaration.
  Syntax Errors: There may be syntax errors in the code that lead to the compiler being unable to determine the type of a variable.
  Inconsistent Data Types: If there are inconsistencies in the data types being used, such as trying to assign a value of one type to a variable of another type without proper conversion.
  Missing Includes or Dependencies: If the program relies on external includes or types that are not available or have not been activated.
  
  Solution:
  
  Check the Code: Review the line indicated in the error message (line &2) and ensure that all variables are properly declared with their types. For example:
  DATA: lv_variable TYPE string.  " Ensure type is declared
  
  Correct Syntax Errors: Look for any syntax errors in the surrounding code that might affect the compilation.
  Activate Dependencies: If the program relies on other objects (like includes or types), ensure that those objects are activated and do not have any errors.
  Use the ABAP Editor: Utilize the ABAP Editor (SE38 or SE80) to check for syntax errors. The editor will often highlight issues that need to be resolved.
  Check for Type Definitions: If you are using custom types or structures, ensure that they are defined correctly and are accessible in the context of your program.
  Recompile: After making the necessary corrections, try to activate or recompile the program again.
  
  Related Information:
  
  Transaction Codes: Use transaction codes SE38 (ABAP Editor) or SE80 (Object Navigator) to access and edit your ABAP programs.
