What is byte order in SAP BC-ABA - ABAP Runtime Environment?

SAP Term: byte order

• Component: BC-ABA

• Component Name: ABAP Runtime Environment

• Description: The order in which a number having one of the data types i, decfloat16, decfloat34, f, and s or a character in a Unicode system is saved to memory. A distinction is made between big and little endian. In the first case, the highest value byte, and in the second case the lowest value byte, is written to the first position in the memory. The byte order of the current application server can be derived from the static attribute ENDIAN in the system class CL_ABAP_CHAR_UTILITIES.

• Key Concepts: 
  Byte order is a term used to describe the order in which bytes are stored in memory. In SAP, byte order is used to determine the order in which data is stored and retrieved from memory. It is important to note that different systems may use different byte orders, so it is important to ensure that the correct byte order is used when transferring data between systems. 
  
  How to use it: 
  In the SAP ABAP Runtime Environment (BC-ABA), byte order is used to determine how data is stored and retrieved from memory. The byte order can be set using the SET BYTE ORDER statement. This statement takes two parameters: the source byte order and the target byte order. The source byte order specifies the current byte order of the data, while the target byte order specifies the desired byte order of the data. 
  
  Tips & Tricks: 
  When setting the byte order, it is important to ensure that both the source and target byte orders are specified correctly. If either of these parameters are incorrect, then data may be stored or retrieved incorrectly, leading to unexpected results. Additionally, it is important to note that some systems may not support certain byte orders, so it is important to check for compatibility before attempting to set a specific byte order.
