Uploading Opening Balance to RG23A, RG23C & PLA

Dear All,

Can any one explain me in details about uploading of opening balances in RG23A, RG23C and PLA accounts.

I have gone thro' few threads, but my issue is when we need to update these J_2IACCBAL and J_2IRG1BAL tables. I mean before uploading opening stock thro' 561 or after uploading the initial stock.

Please help...

Regds,

CB
