Hello,
1. You can migrate P&L account when cut off is during the year. This means you migrate balances or each document at P&L with CO information like cost centers
Or you just post P&L balance (one sum) against equity. The result is the same in accounting, but what is the requrirement of customer?
2. The SAME: at year end you CAN migrate P&L information of the year with CO information for comparison in the following year for each document.
Or you just make one Posting (one sum) against Equity.
3. Just posting balances of balance sheet accounts is not a good idea.
On one hand you might loose information on the other hand behind these balance accounts are sub ledgers like AR, AP, FA, Accrued Liabilities,....
I tried to draw a picture to show some connections of this topic.
Please let me know if I have met your expectations and if you have some further queries.
Post script: In project you might make several interim accounts per businesss case. Eg interim account FA, interim account AR and one for AP,
this make it easier when you have to take a look about variances. And you have one first control after data import.
Example: sum of AR is EUR 100,.-- after importing data interim account for AR has to show a balance of EUR 100
all the best erwin
