With the launch of SAP s / 4hana 1610, SAP no longer recommends LSMW as data migration tool, but introduces a new tool LTMC. Compared with the traditional LSMW, LTMC changes a lot. SAP consultants may not naturally LSMW. For such a new data import tool, SAP consultants need to master it.


Although I started to touch SAP S4HANA system in 2019, I have used S4HANA system in two projects so far. The first project is an operation and maintenance project of S4HANA. The consultants of the project implementation team still used LSMW tool to import data. The second project is a global rollout project based on S4HANA system. In its global template, all master data is also imported using LSMW. This makes the author have no chance to practice LTMC in these two S4HANA projects.


As a senior SAP consultant, we also need to constantly update the knowledge structure, so the author is determined to master LTMC, a new master data import tool, in order to adapt to the challenges of future projects. In the afternoon, the author found some LTMC tutorials on the Internet, compared with the implementation, and finally successfully implemented LTMC. LTMC imported a master data object, which is the first shot in LTMC practice!


First learn LTMC from a simple master data object, so I selected the master data object source list of SAP MM module. This master data object is relatively simple and has few fields. It is suitable for beginners. I recorded the whole process of the actual LTMC with the following words for reference and correction by peers.
