Hi,
First of all you should understand the accounting standards, in SAP, positive entries are 'Debit' and negative
entries are 'Credit'.
In your case, you have one Debit entry of 123 to the G/L account 18719010 and i guess it is a CENVAT clearing account. Just go to FS00 and check the description of this account.
Now, you have three Credit entries as 120, 2 and 1 because there are three different G/L accounts. One is BED (26361211) = 120, second is Ecess (26361216) = 2 and third is SEcess (26361218) = 1.
