Table Structures and Data Types

Sheet 1: Inventory Schedule (Main Gantt Chart)

• Column A – Task ID: Text (e.g., INV-001), uniquely identifies each task.
• Column B – Task Name: Text (e.g., "Monthly Stock Audit", "Supplier Delivery - Raw Material X").
• Column C – Item SKU: Text (linked to the Item Master List), allows traceability back to inventory items.
• Column D – Start Date: Date format (e.g., 01/05/2024).
• Column E – End Date: Date format (e.g., 15/05/2024).
• Column F – Duration (Days): Number, automatically calculated using the formula: =E2-D2+1.
• Column G – Progress (%): Number (0 to 100), allows manual or auto-updating of task completion status.
• Column H – Status: Text (Dropdown: "Not Started", "In Progress", "Delayed", "Completed"), using Data Validation.
• Column I – Resource Assigned: Text (e.g., “Warehouse Team”, “Procurement Officer”).
• Column J – Dependency Task ID: Text, refers to a parent or prerequisite task (e.g., INV-002 depends on INV-001).
• Column K – Gantt Bar Start Position: Number, used for charting; calculated with =D2.
• Column L – Gantt Bar Length: Number, calculated as: =F2.
• Column M – Visual Completion Indicator: Formula-based cell using a shape or conditional formatting to show percentage completion.

Sheet 2: Item Master List

• Category (C): Dropdown list with options like "Raw Material", "Finished Goods", "Packaging"
• Current Stock Level (D): Number, entered manually or via formula from external systems.

• Lead Time (Days) from Supplier (G): Number
• Last Reorder Date (H): Date format
• Status (I): Text: "In Stock", "Low Stock", "Out of Stock" — auto-generated via formula.
• UOM (J): Unit of Measure (e.g., Units, Kilos, Boxes)

Formulas Required

• =IF(AND(D2<>"",E2<>""),E2-D2+1,""): Calculates task duration.
• =IF(E2<=TODAY(),"Completed",IF(D2<=TODAY(),"In Progress","Not Started")): Auto-updates status based on current date.
• =IF(AND(D2<>"",E2<>""),D2,""): Sets the start of the Gantt bar in the chart series.
• =IF(AND(D2<>"",E2<>""),F2,""): Sets length of Gantt bar.
• =IF(D2="", "", IF(E2: Provides a dynamic status update for tasks.
• =VLOOKUP(C2, 'Item Master List'!A:I, 4, FALSE): Pulls current stock level from the master list (used in Dashboard).
• =IF(D2<>"", E2-TODAY(), ""): Shows remaining days until deadline for overdue tracking.
