Hello Jayant,
You can find in your ABAP F1 help about "byte sequence". The byte sequence determines whether the highest-value byte or lowest-value byte is stored first. In the case of the highest-value byte, the binary display is referred to as big endian and with the lowest-value byte, the display is known as little endian. Different processor might have different byte order.
See example in ABAP help:
Best regards,
Jerry
