LTMC for Master Data Step by Step Process

When We are Implementing SAP S/4HANA solution, We can migrate our master data and business data from SAP systems or non-SAP systems to SAP S/4HANA. By using  SAP S/4HANA migration cockpit.

The SAP S/4HANA migration cockpit uses migration objects to identify and transfer the relevant data. A migration object describes how to migrate data for a specific business object to SAP S/4HANA. It contains information about the relevant source and target structures, as well as the relationships between these structures. It also contains mapping information for the relevant fields, as well as any rules used to convert values that are migrated from source fields to target fields. SAP provides predefined migration objects that you can use to transfer your data.

The Tool used to perform Migration is LTMC – (Legacy Transfer Migration Cockpit)

You can access the SAP S/4HANA migration cockpit by using transaction LTMC.

Note the following considerations when deciding on the most suitable approach for your project:
Consideration Files Staging Tables 
Size Limit  200MB limit for SAP S/4HANA Migration Cockpit .*  No Limit. 
System Considerations  None.  Staging system uses an SAP HANA database. 
Data Provisioning Enter data manually in each Microsoft Excel XML file.  Fill tables manually or by using preferred tools (for example SAP Agile Data Preparation). 

* For on-premise systems, parameter icm/HTTP/max_request_size_KB controls the size of the http request. The value of this parameter is the maximum size (in KB) of an HTTP request. This parameter has the standard value 102400 kb (100MB) but can be changed if required.
