Due to audit purposed, we are required to produce a trial balance report for period 01/01/2012 - 31/12/2012, We discovered that the report that generated wasn’t tally in figures while comparing the opening and closing between the 2012 vs 2011 fiscal year , mainly due the missing period of opening (period code ) 01/01/2013 - 01/01/2013 -(Status=Closed).

General Ledger > Setup > Periods >Periods

scenario : The current period is 05/2013

Question :

  1. Can i delete the fiscal year of 2012 -2013 and then creating a new fiscal year for 2012 -2013 again , Would this be a solution . Any problem on this solution ?

  2. Is anyone can give a hand on this problem ?
