DDIC Structure for Migration Cockpit Objects

[Victorvk]

Hello,

we are trying to export data from our sap system to another sap system using the CSV files generated by the S/4 HANA Migration Cockpit. Thes file format is based on specific table structures as seen in image below (in this example for the customer object):

The issue is that we cannot find any corresponding DDIC structures such as "S_CUST_GEN". Do these table structures exist within the SAP System? Or is there a piece of code where these structures are dynamically created from where one could copy them to a DDIC structure?

Thank you, Victor

Hello Viktorvk,

the sender structures S_* are no DDIC structures, they only exists as  entries within the migration workbench configuration tables.

The structures are then generated into the coding. But each sender structure of a migration project is available as temporary table on the SAP HANA database: 
If you are an on-premises or Private Cloud customer you will see that tables within SE11 per migration project. You need to have the three letter Mass transfer ID of your project. The naming convention of a structure is as follows:

see 2733253 - FAQ for SAP S/4HANA migration cockpit. Migration approach: Transfer / Migrate data using s...

• 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 is to search for then name via description.

The last two fields are not part of the sender structure, they are status flags for the data migration. Also the first field MANDT is not part of the defined sender structure
