Hi Vineet,
The revaluation is a 2 step process and every month end these 2 steps need to be executed:
Ensure that the document date/posting date (depending on OB22 config) currency rates are different than the period end date currency rates. Otherwise there is no FX reval postings.
On F.05 tcode there is header data and also tabs:
0) Use/create a Valuation Method through OB59 with "Always revaluate" option
1) In the header data select the "Valuation in Curr type = "30", depending on how you configured the OB22 tcode for the company code mentioned.
2) In "Postings" tab, check "Balance Sheet prep valuation"
3) "Open items" , select the BSheet accounts to be revaluated. These accounts need to be configured in OBA1 tcode fo5r automatic postings with KDF key.
4) In "G/L balances" tab you will see the accounts already in the Open Items tab and at a minimum check "Valuate G/L balances"
5) In "FASB 52" tab:
a) Execute 1st the option "Translate valuation difference" (note the results)
b) Execute 2nd (uncheck the (a) above and check "Use translation" (note results & posting)
In addition to the above please check the below wiki page for a lot of information about FX reval process:
