The AR users reported an issue about reconciling AR subledger to the G/L. In Business Central, subledger control accounts (like Accounts Receivable and Accounts Payable) must not be posted to directly; they should only be posted through transactions (invoices, payments).

If Direct Posting = Yes, users can post directly into AR or AP control accounts, which causes reconciliation issues.

To prevent this, you set Direct Posting = No on the G/L Account Card for control accounts.

Why not others:

A. Switch Blocked on the Customer Card → Blocks transactions but does not solve reconciliation issues.

B. Switch Direct Posting on the G/L Account Card to Yes → Makes the issue worse.

C. Switch Blocked on the G/L Account Card to Yes → Prevents all postings, even system ones, which is incorrect.

Correct answer: D. Switch Direct Posting on the G/L Account Card to No
