stock valuation

We have done following setting for Stock Valuation.

1)In transection code OMWE we have done LIFO valuation not active and FIFO

valuation active.

2)In 2nd step TCODE MRLH we are getting "LIFI Valuation is not defined"

Please guide us what could be the reason.

Note:

Before that we need to set the FIFO/LIFO valuation for Valuation area like CCode/Plant.

Please sugest me

Rgs,
