Difference in period 08 and 09 was caused by the account 13101 which was dedicated for Equity Elimination Exchange Differences ( I have attached document from period 08 and same applicable for period 09)

Up to period 07, there are only two entries available from account 13101 under on consolidation node group "GRP-SE83 - GRP-SE93 - IGT Holding III Sweden AB" and after 2023-08, it is 3 entries. This additional entry is the exact difference as well
