Excel Template for Data Collection Supply List (Data Version)

This comprehensive Excel template is specifically designed for Data Collection purposes within supply chain and inventory management contexts. It serves as a dynamic Supply List that supports real-time tracking, version control, and data integrity through its dedicated Data Version structure. The template enables organizations to maintain accurate records of supply items, monitor stock levels, track revisions over time, and generate actionable insights using built-in formulas and visualizations.

Sheet Names

• Supply List (Data Entry): Main data collection sheet for inputting and managing supply items.
• Data Version Log: Tracks changes, versions, timestamps, and responsible users for audit purposes.
• Summary Dashboard: Provides real-time analytics with charts and KPIs based on the collected data.
• Instructions & Guidelines: Contains user guidance, data validation rules, and template usage instructions.

Table Structure in "Supply List (Data Entry)" Sheet

The primary table is structured as a dynamic Excel Table with the following columns:

Columns and Data Types (Detailed)

• Item ID (Text, Unique): A unique alphanumeric code assigned to each supply item (e.g., SL001, SL-005). Ensures no duplicates.
• Item Name (Text): The full name of the supply item (e.g., "Stapler - Black", "A4 Paper - 80gsm").
• Category (Text, Dropdown): Categorized using a data validation list: Raw Materials, Packaging, Tools, Consumables.
• Unit of Measure (Text): Standard unit used for inventory tracking (e.g., "pcs", "kg", "box").
• Current Stock Quantity (Number): Integer value representing available units.
• Reorder Level (Number): Threshold quantity at which a reorder should be initiated. Auto-calculated or set by user.
• Last Updated (Date): Automatic timestamp of the last edit to this row (uses formula).
• Status (Text, Dropdown): Options: Active, Low Stock, Out of Stock, Discontinued.
• Supplier Name (Text): Name of the vendor providing the item.
• Lead Time (Days) (Number): Average time in days to receive a new order after placing it.
• Data Version ID (Text, Auto-incremented): Unique version tag assigned during data updates, used for audit trails.

Formulas Required

The following formulas are applied in the "Supply List (Data Entry)" sheet to support automation and validation:

• =NOW(): Used in the "Last Updated" column to auto-populate timestamp when any cell is edited. Protected with conditional formatting rules.
• =IF([@Current Stock Quantity] < [@Reorder Level], "Low Stock", IF([@Current Stock Quantity] = 0, "Out of Stock", "Active")): Dynamically updates the Status column based on stock levels.
• =TEXT(NOW(), "YYYY-MM-DD") & "-V" & COUNTIF(DataVersionLog[Version ID], "*"&"*") + 1: Generates unique Data Version IDs when a row is updated (linked with the Data Version Log).
• =IF(AND([@Current Stock Quantity] < [@Reorder Level], [@Status]="Active"), "Reorder Needed", ""): Adds a flag for items requiring replenishment.

Conditional Formatting

To enhance visual data interpretation and user awareness:

• Low Stock Highlighting: Cells in the "Current Stock Quantity" column turn yellow if below the Reorder Level.
• Out of Stock Marking: Red background with white text for items where stock equals zero.
• Status Column Coloring: Green for "Active", amber for "Low Stock", red for "Out of Stock".
• Last Updated Column: Light blue background if updated within the last 7 days; gray otherwise.

User Instructions

1. Open the template in Microsoft Excel (version 365 or later recommended).
2. Navigate to the "Supply List (Data Entry)" tab for data input.
3. Enter new supply items using valid data types and dropdowns. Do not delete rows; use filters to hide unwanted entries.
4. Always update the "Last Updated" timestamp—this field auto-updates on edit but ensure edits are saved properly.
5. When a major change (e.g., price, supplier, reorder level) is made, verify that a new Data Version ID is assigned in the corresponding row.
6. Check the "Data Version Log" tab to see historical changes and revisions. This ensures traceability for audit purposes.
7. Use the "Summary Dashboard" tab for real-time performance metrics and visual trends over time.
