LTMC Maintenance Plan Load – Error in Mapping of Maintenance Item Category (T399P/MITYP)

During the Implementation SAP S/4HANA solution, SAP provides us with the standard migration tool called as LTMC (Legacy Transfer Migration Cockpit), using this tool we can migrate our master data and business data from SAP systems or non-SAP systems to SAP S/4HANA.

In the S/4HANA migration cockpit we use migration objects to identify and transfer the relevant data.

For each migration object, a predefined template with detailed of each field is available

When processing the LTMC (Migration Cockpit) to load the Maintenance Plan, we fill in the predefined template and load the data.

This blog is to share an issue encountered while loading a Maintenance plan through LTMC and the fix that was found out subsequently.

Issue Encountered:

In the convert value step, when we are executing for the first-time for Maintenance plan object in a project, we need to Map fields.

We need to click each line item and do the correct Mapping of Values between the target field to the source field.

One of field mapping error encountered is “Mapping for Maintenance Item Category”, when we try to click open and try to do a mapping by selecting the F4 help on the “S4HANA Target Value Field” we get an error of “No result found in the S4HANA Target Value”

When you try to manually input the Maintenance Item Category value of same as the value of Maintenance Plan category (in our Example “PM”), we get an error as “PM is not a valid value of Table T399P (field MITYP)”

Unless the above error is resolved we will not be able to proceed further with the data migration for the Maintenance Plan object

Reason for this Issue:

The value check table for “Maintenance Item Category” in the translation object MAP_MITYP is having a wrong value as MITYP and MITYP has wrong domain rule.

Solution for this Issue:

The value check table for “Maintenance Item Category” in the translation object MAP_MITYP must be corrected manually following the below steps.

In LTMOM, open your migration project and expand the Translation Object node

Click Translation Object MAP_MITYP (1), press the change button (2) and Click Change for Export Parameter (3)

Change the value table T399P to T399W, and Change field MITYP to MPTYP

Click Enter and Save

Open your Migration Object and Click Generate run-time Object and Exit

Post these changes rerun the migration object again in LTMC and now the Maintenance plan data should be migrated without any issue.
