Dear SAP Friends,

Welcome to another interesting blog.

With continuation to the previous blogs

LTMC replaced with Migrate Your Data | SAP Blogs

LTMC replaced with Migrate Your Data (2/2) | SAP Blogs

In this blog will see changes that have been made to Migration Object Modeler,

As discussed in previous blogs from 2020 version changes have been made to Migration cockpit, and now 2 only approaches are there in Migration Cockpit.

  1. Migrate data using staging tables (file/staging)

  2. Migrate data directly from the SAP system

With reference to both approaches changes happened to the Migration Object Modeler (LTMOM)

Now let’s see changes for LTMOM in Migrate Data Using Staging Tables

Flexible and extendable

  • Copy migration objects

  • Adjust standard migration objects (for example add fields)

  • Simulate/debug import of data from staging tables

  • Create user-defined migration objects

  • Use standard APIs or code your function module

  • Create or edit translation objects and rules

  • New*: Export/import a project from one system to another system

  • New*: Use project in a different client

  • New*: Reset transfer status

*This does not apply to projects created with LTMC.


Export/import projects

Before SAP S/4HANA 2020: You export/import projects using transaction LTMC.

As of SAP S/4HANA 2020 and for projects created with the Fiori App: You export/import projects using transaction LTMOM (migration object modeler).

Export / Import projects

If the project you are importing does not exist in the system, a new project will be created with the relevant project settings.

If the project you are importing already exists in the system, the existing project settings will be overwritten with the exception of the following:

  • Database connection

  • Job settings

  • Retention period settings


For projects created with the new Fiori App, the following applies:

1. Client Dependency: Projects can only be seen and changed in the client where the project was created.

2. Using a project in a different client: It is possible to use a project in a different client, the project is not copied, but only available in the new client; all mapping tasks are deleted.

3. Non-modifiable systems / productive systems: It is not possible to modify projects in non-modifiable / productive systems. If you need to adjust (for example delete a migration object), you can adjust the project in the development system and export/import it again to the productive system.


New namespace for customer structures and fields introduced with 2020 FPS01

Source Structure

  • The name of a source structure must begin with “ZS_”

  • This applies to source structures that are added by the user to a migration object which was copied from the template

Source Structure Fields

  • The name of a source structure field must begin with “ZZ”

  • This applies if the source structure field is added by the user to a migration object which was copied from the template

It is possible to reset the transfer status for a migration object: The report DMC_MC_FM_RESTART_HANDLE resets the transfer status of all selected records in the staging tables or uploaded MS Excel XML files.

Reset the transfer status

Projects created using old app transaction LTMC (Web Dynpro) cannot be converted to the new SAP Fiori app but will be available as read-only from 2105 onward and from 2021 onward for the on-premises products.


Projects created in transaction LTMC:

  • Are classified as “old” in the migration object modeler (LTMOM)

  • Can still be changed and worked within the migration object modeler in SAP S/4HANA 2020, but can only be used in transaction LTMC

Projects created in transaction LTMC


Changes in Migration object modeler for Direct Transfer Approach

1. One harmonized user experience using SAP GUI UI for all approaches

2. Transport: add projects, objects, and rules to transport requests

3. Copy and delete migration objects

4. Selection: skip rule; inherit restrictions within the data model

5. Create source code rules; custom-created mapping rules automatically filled with mappings

6. Debugging capabilities for transformation and simulation (since 1909)

7. Finished projects in display mode only
