LIFO/FIFO indicator for movement types

Hi!

I am facing problem in calculating the FIFO valuation inventory.

Actually I don't want to include movement types 162,541&542, accordingly I have removed LIFO/FIFO flag in OMJJ.

But while executing MRF1, whether the LIFO/FIFO flag is checked or not checked it is considering for FIFO valuation. for the movement types 16t2,541,542, Quantiy & value updation flags both have been checked.

Please any one can guide me???
