FIFO valuation is not updated by system

Question

Hi,
We have activated FIFO valuation and all configuration was set. We done MIGO with different rate and Consumption also done.
Month end we have don e the following process
MRF4,MRF3 and MRF1
the result is system is taking the moving average price only instead of FIFO valuation.
Goods Receipts
Qty     price     value     MAP
100     100     10000     100
150     120     18000     120
200     180     36000     180
450          64000     142.22
Issues :               
100     142.22     14222.22     142.22
150     142.22     21333.33     142.22
250          35555.55     142.22
200     0     28444.45     142.22
As per FIF the following is the rate system to take and post
200     180     36000     180
But system is takinf 200 * 142.22 = 28444.45
can anyone guide me to solve this issue.

HI,
check if you hve set the "single receipt" flag in your FIFO valuation method (T-code OMWP). For explanation whats the difference if the marker is set or not see

Check also the "tolerances" setting in MRF1, maybe its made in a way that the FIFO result is not taken into consideration but the material price is taken instead.
