Hello, Jain.
Have you check tr. TRLCCHK ? This transaction check you configuration and it might help you.
As concerns error GU444 - there are a few issues about this error and all concern ledgers and ledgers group. So check these transactions. if they configuraed correctly? By the way, do you have parrallel accounting in TRM?
1. SM30 -> TRGV_TAC_VA - check if everythig is okey here, if accounting principles are assigned to all you valuation areas.
2. SM30 -> V_TACC_PRINCIPLE - check if all accounting principles do exist.
3. SM30 -> V_FAGL_TRGT_LDGR - Check ledger groups if they assigned to accounting principle
4. SM34 -> VC_FAGL_LDGRPMAP - Check what's inside the ledger group.
5. SM30 -> V_FAGL_T881 - check if all needed ledgers are defined. One of the ledger must be leading.
6. SM30 -> V_FAGL_T882G - if you have parallel accounting - you have to define non-leading ledgers.
