Introduction

  • Presenter: Vikram
  • Channel focus: SAP S/4HANA functional topics, particularly logistics and finance.
  • Topic of discussion: LT MC as an enhanced version of LS MW (Legacy System Migration Workbench).

Understanding LT MC

  • LT MC Definition:
    • A new version of LS MW, providing enhanced functionality for migrating data from legacy systems to SAP S/4HANA.
    • Useful for uploading master data and transactional data from older ERP systems (e.g., Tally).

Importance of LT MC

  • Why Use LT MC:
    • Avoids manual data entry for large volumes of data (e.g., thousands of customers).
    • Supports automated uploads of various data types like GL accounts, cost centers, and profit centers.
    • Recommended tool over LS MW for SAP S/4HANA.

Accessing LT MC

  • Accessing the Tool:
    • Transaction Code: LT MC
    • Opens in a web browser (recommended: Google Chrome).
    • Navigates to "Migrate Your Data" screen.

Creating a Migration Project

  • Steps to Create a Migration Project:
    1. Create a new project (e.g., Z_Cost_Center).
    2. Select and create migration objects within the project (supports multiple objects).
  • Example Migration Object:
    • Cost Center: Click on the object, confirm with "OK" to generate in the background.

Uploading Data Using LT MC

  • Download Template:
    • Automatically provides a download template with pre-defined fields.
    • Allows for easier mapping of fields compared to LS MW.
  • Filling the Template:
    • Users fill mandatory fields (marked with a star) in the downloaded Excel template.
    • Optionally add additional fields as needed.

Enhancing the Template with Z Fields

  • Z Fields:
    • Custom fields added by consultants can be included in the migration template.
    • Use the Migration Object Modeler (transaction code: LT M OM) to add Z fields to the template.
  • Example of Adding Z Field:
    1. Insert new field in migration object modeler.
    2. Specify data type and length.
    3. Generate the object to reflect changes in the template.

Uploading the Filled Template

  • Uploading Process:
    1. Return to LT MC and upload the filled file.
    2. Activate the uploaded file.
    3. Start the transfer process, during which data is validated.
    4. Confirm mappings between source and target fields.
    5. Execute the actual import to upload data into SAP S/4HANA.
  • Validation Messages:
    • System provides feedback on errors, warnings, or success during the process.

Finalizing the Migration

  • Post-Migration Steps:
    • Verify uploaded data using transaction code KS03 (display cost centers).
    • Option to finish the migration object or continue uploading additional data.

Conclusion

  • LT MC streamlines the migration process for legacy data in SAP S/4HANA.
  • Encouraged to subscribe to the channel for more insights and tutorials on SAP S/4HANA logistics and finance topics.
