Table Structures and Data Types

1. Inventory Master List (Sheet: 'Inventory Master')

This table serves as the foundation of the entire system. | Column Name | Data Type | Description | |------------------------|-------------------|-----------| | Item ID | Text/Number | Unique identifier for each product (e.g., I001, I002) | | Product Name | Text | Descriptive name of the item (e.g., "Blue Widget A") | | Category | Text | Grouping (e.g., "Raw Materials", "Finished Goods") | | Current Stock | Number | Real-time count on hand | | Reorder Point | Number | Threshold triggering a new purchase order | | Lead Time (days) | Number | Average time from order to delivery (in days) | | Supplier | Text | Name of the vendor or supplier | | Unit Price | Currency | Cost per unit in local currency |

2. Reordering & Delivery Schedule (Sheet: 'Reordering Schedule')

Tracks purchase activities and delivery timelines. | Column Name | Data Type | Description | |------------------------|-------------------|-----------| | PO Number | Text/Number | Purchase order reference number | | Item ID | Text/Number | Links to Inventory Master List via lookup | | Order Date | Date | When the PO was issued | | Expected Delivery | Date | Calculated as: Order Date + Lead Time (days) | | Actual Delivery | Date (optional) | To be filled upon receipt | | Status | Text (Dropdown) | "Placed", "In Transit", "Received", "Delayed" |

Formulas Required

- **Expected Delivery Calculation:** `=IF([@Order Date]<>"",[&Order Date] + [@Lead Time (days)], "")` This formula auto-calculates the expected delivery date based on order date and lead time. - **Reorder Trigger Alert:** `=IF([@Current Stock]<=[@Reorder Point], "REORDER NEEDED", "")` Flags items that have fallen to or below their reorder threshold. - **Status Update Logic (for Delivery Status):** `=IF(AND(@Actual Delivery<>"", [@Expected Delivery]<@Actual Delivery), "Delayed", IF(@Actual Delivery<>"", "Received", IF(TODAY() > [@Expected Delivery], "Overdue", "In Transit")))` This dynamically updates status based on actual and expected delivery dates. - **Gantt Chart Start & End Dates:** Use the `Order Date` and `Expected Delivery` fields to create start and end values for chart bars in the Gantt sheet.

Conditional Formatting

To enhance visual clarity:

Overdue Deliveries: Apply red fill with white text if TODAY() > Expected Delivery.
Reorder Alerts: Highlight rows in yellow if current stock ≤ reorder point.
Delayed Items: Use orange highlight for any PO marked as "Delayed".
Gantt Chart Bars: Color-code bars by status: green (Received), blue (In Transit), red (Overdue).

User Instructions

Setup: Enter all inventory items into the 'Inventory Master List' with accurate stock levels and reorder points.
Add POs: In 'Reordering Schedule', create a new row for each purchase order using the Item ID to link to master data.
Update Status: As shipments arrive, update the 'Actual Delivery' field and let formulas auto-update status.
Analyze Dashboard: Review KPIs like total reorder alerts, average lead time, and overdue deliveries on the Overview Dashboard.
Generate Gantt Chart: The chart updates automatically based on order dates and delivery timelines. Use it to identify bottlenecks or plan future orders.
