LTMC for Master Data Step by Step Process

Dear All,

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 160MB 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. For more information, see

https://help.sap.com/viewer/fe1dfb6e6c551014b6f1befabc903d5d/7.02.19/en-US/483e87b3ca6b72d0e10000000a42189c.html

Steps to Use LTMC

  1. Enter LTMC T.Code

2. LTMC Web page / Fiori App will get opened

3. Click on Create for Starting New Migration Project

 

4. Provide Project Title & Data Retention Time and hit Create

5. In the Search bar, we can look for an object which we want to use and upload data

6. Select Required Object and click open

It’s just an information  and press ok

7.  Click on Download Template so XML file will be downloaded

8. A pre-filled Template with detailed of each field and business is available

9. In Field, List Sheet will find each sheet which and all are mandatory  based on that we will fill data and upload

10. In Basic Data Sheet highlighted column is mandatory and fill the remaining fields and sheets as per requirement.

      Hi Ruthvik

      I need a way to create QM views for a bunch of materials in mass.

      Is there a standard template available for the same?

      Under the older LSMW, I would have created a recording of MM01, where I select the QM view for the required plant and proceed with maintaining the fields which I wish to update for my materials.

      In fact, I need to update only these four fields for my material-plant combinations:

      MARA QMPUR QM in Procurement is Active
      MARC SSQSS Control Key for Quality Management in Procurement
      MARC QMATA Material Authorization Group for Activities in QM
       
      MARC KZDKZ Documentation required indicator

      Can you guide me as how to go about it? is there a standard way to extend a particular view in MMR , in my case , the QM view?

      Any inputs will be appreciated.

      Hi Ruthvik,

      Excellent document.

      I have a small doubt in Material Load. My question is if we are loading different material types then we have the different views( Raw Material - No Sales views required, FERT - required all views). How to handle this in a single file?

       

      Thanks in advance.

       

      Regards,

      Venkat.

      LTMC will automatically detect views based on material type no need to maintain manually based on information we maintain views will get selected

      Hi Ruthwik

      LTMC is out good old friend. Quite innovative one is it, indeed.

      I just looked at CVT_MATNR, starts with statics: ... well, I am prepared to find go to as well.

      We still have a bad clue that 65% and 83% are somehow hardwired...

      Regards
