SAP S/4 Practical LTMC Data Migration Cockpit
Article Directory
foreword
The actual operation environment is s/4 1809. In the S/4 environment, LTMC is officially recommended to replace LSMW. However, LSMW can still be used. However, considering the version update, some functions may be affected, so Begin to learn how to use the new LTMC. This article is to record and summarize the current use records of LTMC and the pitfalls I have stepped on. Because I am also just starting to use it, there may be some that have not been written or have fallacies. You can share them together. Discuss the solution.1. What is LTMC?
LTMC = Legacy Transfer Migration Cockpit, there are mainly two transaction codes, LTMC and LTMOM.
It can be opened directly in the GUI with transaction code LTMC or spell URL.
2. Use steps
1. Configure SICF and enable LTMC service normally
In this test, I encountered the situation that LTMC could not be enabled normally after configuring SICF. After repeated research on HOSTS and server IP, the problem could not be solved. The IE browser enabled with LTMC always showed that it could not be opened. My hosts file is Added a record of IP+TAB+server host number.
In addition, I used SICF's webgui to test the SAP on the web side, but I couldn't test it, but here I opened it with Chrome. The path of SICF is as follows: At this time,
I began to consider opening it directly with the service path of IP + port + SICF. After splicing Chrome It is true that the Web gui can be opened normally, and then the LTMC transaction code can be used normally. The next chapter will talk about the actual operation record of LTMC;
2. Data Migration
2.1. Create a migration project
First click Create as shown in the figure below to create a migration project, where the ID is a unique transfer ID and will not be repeated. After creation, click the name that appears below to enter the next page.
As shown in the figure below, you can search for templates in the red box here. Note that the feature of LTMC is that the templates cannot be modified. The system provides dozens of ready-made templates. Here is a test of the general ledger account. After searching for the account, download the template to the local, which is a . xml file, but needs to be opened with Excel.
2.2. Data collation
After opening the file, you can see that there are several data theme sheet pages in the red box, and those marked with * must be lost. At the same time, the test found that some rules are different from those created by FS00. For example, when I create the account of the primary cost element of P, when I also fill in the cost element category, I also need to fill in the validity period and cost control range, otherwise it will not pass the verification.
In addition, it is only possible to automatically fill in the leading 0 for the subject here. The length of my custom subject is 00000000 to 99999999, and the 8-digit subject cannot pass the verification. You must use a subject similar to 0012345678.
Once completed, the file can be uploaded. After uploading it needs to be activated and then transferred.
In addition, there is one point that needs to be explained here, that is, if you want to change a version of the file, you need to select it here, and then delete it, and you cannot directly upload the file to overwrite it.
Perform the first step of verification, the information displayed here indicates that there is no error.
The second step here is all green lights, if it is a red light, you can select the wrong entry and click "Process Task" to modify it;
The third step is to simulate the upload. There is no error message here, indicating that the upload can be performed.
After the upload is completed, you can see that it is displayed here as completed, and at the same time it cannot be deleted or canceled. This has the advantage that it can be compared, and the uploaded data has log records.
Summarize
This article is a simple test and exercise that took a little time to do. I will continue to test and record the problems encountered later.
