tSM Stock Management

The tSM Stock Management module provides functionality to manage and track material stocks, including:

  • Different stock types (central, local, project, consignment, personal, etc.),
  • Item-level details (serial numbers, batch numbers, etc.),
  • Stock movements (inbound, outbound, transfers, issues to tasks),
  • Shared responsibility or ownership among multiple users.

This module can be tightly integrated with existing ERP solutions via synchronization or serve as the primary stock-management system for smaller-scale deployments.


1. Module Overview

Purpose and Scope

  • Material/Equipment Tracking: Keep an up-to-date record of items in multiple stock locations.
  • Support for Various Stock Types: Central, project-based, consignment, or personal.
  • Integration with WFM Tasks: Technicians can issue or return items directly from their assigned stocks while performing field tasks.
  • ERP Synchronization: Optionally synchronize stock data with an external ERP (e.g., SAP) to maintain consistency in master data.

Key Features

  • Create & Manage Stocks: Define new stock repositories; set status (active/inactive), type, and ownership/responsibility.
  • Item-Level Details: Track quantities, serial numbers, batch numbers, and pricing.
  • Movements and Transfers: Record inbound/outbound material movements, linking them to tasks or other destinations.
  • Shared Responsibility: Multiple users or roles can be associated with a single stock.
  • Code-Table Customization: Stock types, movement types, and item types can be extended or tailored to specific needs.

2. Core Functionalities

2.1 Stock Creation and Management

  • Define a Stock with attributes such as owner, status, type, and whether it’s a default stock.
  • Optionally assign multiple Shared Responsibilities (other users who can manage or access that stock).
  • Mark stocks as Active or Inactive to control usability.

2.2 Item Management

  • Stock Items capture the existence of a material or device in a particular stock.
    • Can store amount, price, serialNumber, or batchNo.
    • Each item can be associated with a StockItemType (e.g., a category for modems, cables, etc.).
    • Items have a status (active, archived) to handle lifecycle states.

2.3 Movements

  • Stock Movements allow transferring items between stocks, issuing items to tasks, or returning items from tasks.
    • Each movement references a StockMovementType (e.g., “Receipt,” “Transfer,” “Issue to Task”).
    • Statuses (new, canceled, or sync states) track the progress or synchronization outcome.
    • Movements can be “storno-ed” (canceled/reversed) when corrections are needed.

2.4 Synchronization with ERP

  • The module supports two-way synchronization with external ERP systems for:
    • Stock definitions, statuses, and ownership.
    • Item catalogs, serial numbers, and movement records.
  • This ensures technicians in the field and back-office staff always see accurate, real-time stock data.

3. Integration Patterns

  1. WFM/Tasks Integration

    • When a technician starts or completes a task, they can issue or return materials to a stock.
    • The “Moves” or “Movement creation” UI or API ensures each item’s quantity is updated accordingly.
  2. ERP Systems

    • Synchronize newly created or updated stock definitions, item details, or movement records to an ERP.
    • Regular updates from ERP to tSM can refresh stock item statuses, new item catalogs, or location changes.
  3. CRM/Ordering

    • Some scenarios may require that new orders or service requests trigger stock reservations or item picks.
  4. Reporting

    • Summaries of stock usage, movement history, or item availability can feed into analytics tools for replenishment planning or cost tracking.

4. Example Use Cases

  1. Central Stock & Field Technician

    • A central warehouse (defined as a Stock) supplies items to technicians’ personal stocks.
    • Technicians mark items as “Issued to Task” while on-site to track consumption.
    • If leftover materials remain, they can be returned to the personal stock or transferred elsewhere.
  2. Consignment Stock

    • A supplier owns the stock at the telco’s site until items are consumed.
    • The tSM Stock Module tracks movements between the consignment location and active deployment, ensuring accurate usage and billing.
  3. Project Stock

    • A dedicated stock for a particular project or customer contract.
    • Items are only used for that project’s tasks, and any leftover is transferred back to central or reallocated.
  4. SAP Integration

    • Stock definitions, movement types, and item catalogs are mastered in SAP.
    • tSM pulls them regularly for WFM usage.
    • Any new item usage records or newly created stocks (like personal or temporary sites) are pushed back to SAP for consistency.

5. Best Practices

  • Define Clear Stock Types
    • Keep code tables well-documented (e.g., “CENTRAL”, “LOCAL”, “PERSONAL”) to ensure consistent usage across systems.
  • Automate Movements
    • Encourage technicians to use the mobile or task interface for any materials they handle, rather than offline logs. This ensures real-time updates.
  • Implement Duplicates/Serial Check
    • For serial-controlled items, ensure unique serials are enforced to avoid data conflicts.
  • Regular Sync with ERP
    • Schedule frequent synchronization to catch stock changes from other departments and reflect them in field operations.

6. Conceptual Entity Model

Below is a high-level Mermaid diagram illustrating the primary Stock entities and their relationships:

Diagram Explanation

  1. Stock represents a repository of items; it references a StockType and has a StockStatus. One or more SharedResponsibility records link additional owners or users.
  2. StockItem belongs to a specific stock and can be classified via StockItemType. Its StockItemStatus reflects lifecycle states (e.g., active vs. archived).
  3. StockMovement tracks transfers (inbound or outbound) between items/stocks, referencing a StockMovementType and carrying a StockMovementStatus.

7. Entity Highlights

7.1 Stock

  • Business Role: Represents a physical or virtual location where items are stored. Examples: Main Warehouse, Technician’s Van, Consignment Storage.
  • Key Attributes:
    • status (ACTIVE/INACTIVE) dictates if the stock is currently usable.
    • stockType references StockType for classification.
    • ownerUserId or SharedResponsibility define who manages it.

7.2 StockItem

  • Business Role: An actual item or batch in a stock (e.g., 5 units of cable or a single modem with a specific serial number).
  • Key Attributes:
    • amount or quantity.
    • serialNumber, batchNo for traceability.
    • stockItemType references StockItemType.

7.3 StockMovement

  • Business Role: Any stock change event—receiving goods, transferring them from one stock to another, or issuing them to a task.
  • Key Attributes:
    • stockItemFrom and stockItemTo for origin and destination references.
    • movementType references StockMovementType (e.g. “TRANSFER,” “ISSUE_TASK”).
    • stornoMovement indicates if it’s a reversal/cancellation.

7.4 SharedResponsibility

  • Business Role: Provides a flexible way for multiple users to share or overlap management of a single stock.
  • Key Attributes:
    • stock references the stock’s key or code.
    • validFrom / validTo define the period in which this responsibility applies.

7.5 Code Tables (Types & Statuses)

  • StockType: Standard or custom categories of stocks.
  • StockItemType: Defines categories for items (e.g., “Router,” “Cable”).
  • StockMovementType: Distinguishes movement scenarios (transfers, issues to tasks, receipts).
  • StockStatus, StockItemStatus, StockMovementStatus: Basic enumerations or code tables marking lifecycle states (Active, Inactive, New, Canceled, etc.).

8. Use in Work Force Management

The Stock Module is closely tied to Work Force Management (WFM). For example:

  • A field technician needs to have a personal or local stock assigned.
  • While completing a task, the technician “issues” an item from their stock to the task. This triggers a StockMovement record that updates both the WFM task status and the stock’s available quantity.
  • If an external ERP is in use, the movement record is synchronized so back-office staff see accurate item usage and can reorder or replenish.

9. Future Directions

  • Primary ERP Role: Currently, tSM Stock often complements a main ERP, but upcoming enhancements may let tSM serve as the primary stock system for telecom operators who lack an external ERP.
  • Advanced Inventory Controls: Features like automated reorder points, min/max stock levels, or advanced batch/lot tracking can be added to further expand stock management capabilities.
  • Mobile-First Enhancements: Streamlined app workflows for technicians to scan and update items via QR codes or NFC.

10. Summary

The tSM Stock Module provides a robust yet flexible framework for managing material inventories within a telecom or field-service context. By defining Stocks, Items, and Movements, it ensures accountability and real-time visibility over critical parts and devices. Coupled with code tables (types, statuses) and shared-responsibility features, organizations can mirror complex scenarios such as consignment, project-specific stocks, or multi-owner warehouses. When integrated with an ERP, the module keeps both back-office and on-site operations synchronized, reducing errors and improving the overall service delivery process.


In conclusion, tSM Stock is a versatile solution designed to handle a wide spectrum of inventory management tasks—from small-scale personal stocks in technicians’ vehicles to enterprise-grade integration with large ERPs. It is an integral part of the tSM suite, seamlessly blending into Work Force Management scenarios for telecom or similar industries.
