[SAPSupport]

Hi,

In app Migrate Your Data and tcode LTMOM, we can find the object technical names begins with 'Z'. Can you confirm if this is a normal acceptable behavior?

Dear customer,

Yes, this is the standard behavior of data migration

You can check naming convention in KBA 3588725 - FAQ for migration cockpit. Migration approach: Transfer / Migrate data using staging table...

• Below is an example for a generated staging table for object Work center (SIF_WORK_CNTR) and structure S_KAZY

• Table name: /1LT/DS<sys-id><consecutive number>

  • For example: /1LT/DSQKX000928

• Table description: Z_<Alias = technical Object name without SIF_>_<Mass transfer ID>:<structure name>

  • For example: Z_WORK_CNTR_U02:S_KAZY

Best regards,

SAP Support

The main reason for Z migration objects is the following:
SAP delivers standard data migration objects within a standard delivery migration project.

A user creates an own migration project via the migration cockpit and this project is created in customer namespace starting with Z.
Such projects are having the technical name ZSIN_MIG_<mass transfer ID>
For example ZSIN_MIG_NBL.

Adding migration objects to that project, the migration cockpit's framework copies the original SAP migration object (for example, SIF_CUSTOMER_2) into the user's migration project.
The technical name of the copied migration object is as follows:  Z_<ALIAS>_<mass transfer id> 
For example, Z_CUSTOMER_2_NBL
<ALIAS> is the technical migration object name without prefix SIF_
<mass transfer id> is three letter id assigned to a migration project during its creation.

User defined data migration object, also known as custom migration objects, are having prefix Z_Z_

A user always works on a copy of an original object in customer namespace and not on the original object.
