<b>1) Which a/c can be maintained in open item basis what are the requirements?</b>
GR/IR account is an example of G/L account that will be maintained on open item management. Because this account will be getting a credit at goods receipt and exactly same debit will done when corresponding invoice receipt is done. Once matched they can be pushed to cleared items. This helps to keep the account clean, you can only concentrate on open items. The cleared items totals to zero, so you don't have to worry on those transactions.
<b>2) Which a/c can be maintained in Line item basis what are the requirements?</b>
Large accounts like recon account should not be maintained on line item display. this slows the system, if some one looks into line item of these accounts. SAP recommends to avoid this setting for Recon account for AR AP or asset and Tax accounts.
<b>3) What is post automatically only? Why is it used?</b>
If you select, you cannot call this account in simple manual G/L transactions like FB50. Any posting to this account will only be driven by account determination maintained in configuration. Example all those accounts maintained in OBYC like GR/IR account.
