The service mapping tool or SMT in SAP MDG has quickly become a popular choice among people looking to manage their data efficiently. When using an SAP Master Data Governance, your data would be managed by a unique governance process, a standard procedure for them. However, depending on the available data, all its attributes and entities must be configured according to the model the user wants to acquire. There may be a need for more entities or attributes in the data model, which can be controlled or added accordingly based on the wish made by the user. Moreover, you can find various use cases related to SMT mapping that could be helpful to you in SAP MDG.

What is SMT mapping?

If this is your first time using SAP MDG., then you might need a clearer idea about SMT mapping, one of the unique features of SAP MDG. Whenever you are trying to fill in the target structures using a unique combining set of source structures, the program which becomes helpful in carrying out that procedure is known as SMP mapping. Using this SMT mapping feature, you can complete all the processes related to simple mapping, mapping with different field transformations, complex transformations, and various field check mapping.

Moreover, one of this feature’s most significant attributes is converting enterprise-collected data into the internal format of SAP. Many more features are included in SMT mapping, which will be covered in this article. Hence, keep reading this post to understand more about SMT mapping in SAP MDG. Even if you don’t have  any idea, don’t worry, because with the help of SAP MDG Online Certification Training you can get all the requirements a modern IT developer needed.

Features of SMT mapping

Various functions are implemented into the work done by SMT mapping to fill all the targeted structures extracted from multiple authorized sources. Here are all those functions which we have summarised in the points mentioned below.

  •         Only simple mapping

When the work is related to only simple mapping, all the content data inside the source field are copied and put into the targeted field. This unique combination that forms at the end of the procedure between source and target fields is termed 

  •         Simple mapping alongside field transformation

You may already have a clear idea about the simple mapping process. Still, when it is done using the transformation method, which involves converting all the source values directly into the system, it can be termed an entirely different function. However, like simple mapping here in this method, the ratio remains the same as 1:1.

  •         Using just the transformation method

When the system is looking to deploy the transformation method for combining the data sets then, certain specific input parameters need to be provided according to the requirement of the SAP MDG. In such instances, the export parameter is read efficiently by the target fields present in SAP MDG, which are used to complete this process. Hence, when the system software uses the transformation method, the ratio projected between the source and target field is said to be m:n.

  •         Conditions

While using the transformation method, there are many instances where you need help to complete the process accurately. In such scenarios, it is beneficial or crucial for you to meet certain conditions required to complete the procedure. Only if those conditions are met can you close this procedure after it has been finished.

  •         Field checks

 When it comes to putting values in field checks, they are often complicated to fill up. However, if you use the check method provided in SAP MDG, you can complete all these tasks with a simple click. The option of field checking could be really useful to you if you are able to use its qualities perfectly.

  •         XML handling

 Quite a few businesses like to use APIs to change all the data set structures in their system. But if some decide to use something else, SMT mapping of SAP MDG could prove helpful. Using different sets of APIs, your work could have been easy, but choosing one out of all the options could be a heavy task for anyone present. On the other hand, SMT mapping efficiently handles all of this table-based information effectively without bringing much trouble to the user while trying to complete a task as per their requirement.

 Use cases of MDG

SAP MDG is more comprehensive than a few places where it can be used. Moreover, there are quite a few good use cases related to SAP MDG, which you can learn about in detail, as we have discussed everything related to it in the points mentioned below.

  •         Increasing the standard fields

A limited quantity of standard fields present in SAP MDG is used in any work related to data modeling. In such cases, the SAP MDG can add a specific number of standard fields required for the data processing and fill up those spaces that aren’t a part of the system data model. SAP MDG only has the authorization to use some kinds of data models as it is allowed to process and work closely with a specific set of data models. However, you can still add some existing data sets and industry-related solution providers to close the gap created in SAP MDG.

  •         Gaining entrance into the custom fields

When adding to the existing data models in SAP MDG, you can do it in another way, known as customization. A customization feature is a unique option that you can exploit and add data sets as per your preference into the existing data models of SAP MDG. But remember, after editing the data sets, you need to link them with the SAP ERP tables, which will be crucial for maintaining the changes you brought into the data set.

However, a specific number of fields are offered into the data sets for the users to edit as per their requirements, which cannot be extended in any way. Moreover, you can add specific attributes and qualities to your data set, which are considered an even better option if you want to make it desirable.

  •         The flexibility of custom fields

There could be a few instances when mapping in the data fields could get tough for you due to the standard procedures in the SAP MDG data model. When such a thing happens, the custom fields may be unable to bring the changes the user did as per their preference.

Even the option of SMT mapping turns out to be futile when custom fields need help registering themselves effectively. One of the common examples of custom fields includes process-specific fields, which are used explicitly for determining different data sets. The users can change such fields by entering specific data into the models as per their requirements without facing any issues.

Examples of SMT mapping

If you want to configure or write a program in SAP MDG using SMT mapping, then you need to understand the functions and working behind various use cases included in the software. Hence, the best way to understand all of those complex processes would be by closely examining a few examples.

  •         Customizing 

Suppose you use the SMT mapping option to customize the program you have written into the software. Then your first step would be to change the header structure of it and follow it up with the target structure. Once you have completed this process, you need to specify all the operations that are part of the SMT mapping and wait until all the target structures are filled up according to your commands. Customizing could be easy for you, considering all the complexities that come with it.

  •         ABAP program

The ABAP program is another crucial part of the SAP MDG, where you can use SMT mapping to change the source header and target header accurately. Using the ABAP program, all the items in the source document could be changed effectively and efficiently per your preference. A source document comes with many complexities due to the vast number of data conjured up into it. However, using the ABAP program, you can create a loop into the source document to find a source item you could have been looking for a long time. Additionally, SMT mapping is quite an exciting option whenever a source document is worked with inside SAP MDG. 


 It might have been challenging for many people to understand all the concepts related to SMT mapping in SAP MDG as different aspects come into play whenever someone uses the system for their benefit. But after reading this article, you have now understood all the working and feasibility of SMT mapping in SAP MDG.

 It is crucial to remember that SMT mapping is used to fill up all the empty data structures that exist inside of SAP MDG that have yet to be filled up. Hence, if you were also among those who are willing to get a detailed understanding of SMT mapping while also getting to know about SAP MDG, this article has cleared all your doubts.
