In Microsoft Dynamics 365 Business Central, the signs "Cr" (Credit) and "Dr" (Debit) are used to indicate the type of entry for each purchase document. Here is how they typically apply:
1. **Purchase Quotes**:
- No direct impact on the ledger until converted to a purchase order.
2. **Purchase Orders**:
- **Dr**: Inventory or expense accounts (when items are received).
- **Cr**: Accounts Payable (when the invoice is posted).
3. **Purchase Invoices**:
- **Dr**: Inventory or expense accounts (reflecting the cost of purchased items).
- **Cr**: Accounts Payable (recording the liability to the vendor).
4. **Purchase Credit Memos**:
- **Dr**: Accounts Payable (reducing the liability to the vendor).
- **Cr**: Inventory or expense accounts (reflecting the return or correction).
5. **Blanket Purchase Orders**:
- No direct impact on the ledger until converted to a purchase order.
6. **General Journals**:
- **Dr** and **Cr** entries vary based on the specific transaction being recorded.
