Retail Trade Weekly Report Generator - Skill Documentation

Overview

This skill processes multiple weekly sales report Excel files to generate a consolidated Retail Trade Weekly Report with week-over-week (WoW) comparisons across different channels (DRP, DXS, License Store) and product types (Mobile Prepaid/Postpaid, FWA 4G/5G).

Purpose

• Consolidate 12 Excel files (6 current week + 6 previous week) into a single comprehensive weekly report
• Calculate Average Daily Acquisition (ADA) metrics by region and channel
• Compute Week-over-Week (WoW) performance indicators
• Generate formatted Excel output with charts and color-coded performance indicators

Input Requirements

Required Files (12 total)

Current Week (6 files):

1. DRP_Channel_Sales_Report_DRP_M_DD-M_DD.xlsx
2. DRP_Special_SIM_Monitor_Report_Daily_TECNO_M_DD-M_DD.xlsx
3. License_Store_Performance_Monitor_Report_LS_M_DD-M_DD.xlsx
4. DXS_Acquisition_Report_Mobile_Prepaid_M_DD-M_DD.xlsx
5. DXS_Acquisition_Report_Mobile_Postpaid_M_DD-M_DD.xlsx
6. DXS_Acquisition_Report_FWA_M_DD-M_DD.xlsx

Previous Week (6 files with earlier dates): Same file types with earlier date ranges in filename

Store Mapping CSV

File containing Store Name to Region mapping with aliases support:

Store Name,Region,Aliases
SM Megamall,NCR,"Megamall|SM Mega|MEGAMALL"
...

Data Processing Logic

1. File Identification

• Extract date ranges from filenames (format: M_DD-M_DD)
• Auto-group into current week vs previous week based on date comparison
• Validate all 12 required files are present

2. Data Extraction Rules

  • Column 18: Total
  • FWA 5G calculation: Total (Col 18) - 4G (Col 1)

3. Store Name to Region Mapping

# Build mapping dictionary from CSV
store_mapping = {}
for row in mapping_csv:
    main_name = row['Store Name']
    region = row['Region']
    aliases = row['Aliases'].split('|') if row['Aliases'] else []
    
    # Add main name and all aliases to mapping
    store_mapping[main_name.upper()] = region
    for alias in aliases:
        store_mapping[alias.strip().upper()] = region

# Apply fuzzy matching for unmatched stores
def map_store_to_region(store_name):
    # Exact match (case-insensitive)
    if store_name.upper() in store_mapping:
        return store_mapping[store_name.upper()]
    
    # Fuzzy match using substring search
    for key in store_mapping:
        if key in store_name.upper() or store_name.upper() in key:
            return store_mapping[key]
    
    # Default to "Others" if no match
    return "Others"

4. Regional Aggregation

Standard Regions: NCR, SLZ, NLZ, CLZ, EVIS, WVIS, MIN, Others

For each product type and region:

# DRP data: Direct mapping (already by region)
DRP_ADA = drp_data[region][product_column]

# DXS data: Aggregate stores by region
DXS_ADA = sum(dxs_data[store][product_column] 
              for store in dxs_data 
              if map_store_to_region(store) == region)

# LS data: Aggregate stores by region
LS_ADA = sum(ls_data[store][product_column] 
             for store in ls_data 
             if map_store_to_region(store) == region)

# Total for region
RT_Total_ADA = DRP_ADA + DXS_ADA + LS_ADA

5. WoW Calculation

WoW = (current_week_value - previous_week_value) / previous_week_value

# Formatting rules:
# - Display as percentage (e.g., "21%", "-13%")
# - Round to nearest integer
# - Handle division by zero: display "-" if previous_week_value == 0
# - Handle cases where current = 0 and previous > 0: show "-100%"

6. Special Calculations

FWA 5G Components

# DRP FWA 5G
DRP_FWA_5G = Column_10 + Column_11

# DXS FWA 5G
DXS_FWA_5G = Total - Column_1_4G

# LS FWA 5G
LS_FWA_5G = Unli_5G_WIFI_100Mbps + WiFi_4990_SIM

TECNO ADA

TECNO_ADA = CAMON_40 + POVA_7

Usage Example

from retail_trade_report_skill import generate_weekly_report

# Input files directory
input_dir = "/mnt/user-data/uploads/"

# Store mapping CSV
mapping_file = "/mnt/user-data/uploads/store_mapping.csv"

# Generate report
output_file = generate_weekly_report(
    input_dir=input_dir,
    mapping_csv=mapping_file,
    output_path="/mnt/user-data/outputs/Retail_Trade_Weekly_Report.xlsx"
)

print(f"Report generated: {output_file}")

Validation Checklist

Before finalizing output:

• All 12 input files identified and processed
• Date ranges correctly extracted and displayed
• All stores mapped to regions (log unmapped as "Others")
• All WoW calculations completed
• No negative ADA values (except in error logs)
• All formulas validated against sample data
• Charts render correctly
• Color coding applied to all WoW cells
• Total rows sum correctly
• Output file opens without errors

Performance Considerations

• Expected processing time: 10-30 seconds for 12 files
• Memory usage: ~50-100 MB
• Large file handling: Files up to 10MB each supported
• Concurrent processing: Process files in parallel where possible

Troubleshooting

Common Issues

Issue: "File not found" error

• Solution: Verify all 12 files are uploaded and filenames match expected pattern

Issue: Store name not mapping to region

• Solution: Check mapping CSV for typos, add aliases for common variations

Issue: WoW showing "N/A" for all values

• Solution: Verify previous week files are correctly identified (earlier dates)

Issue: Charts not displaying

• Solution: Check openpyxl version >= 3.0, verify chart data ranges

Issue: Negative ADA values

• Solution: Check source data for errors, verify column indices

Version History

• v1.0 (2026-02-02): Initial skill creation
  • Support for 12-file weekly report generation
  • WoW calculations with color coding
  • Store-to-region mapping with aliases
  • Three chart types for visualization
