How To Fix EM324 - Distributor import for migration object &1 only partially possible

SAP Error Message - Details

• Message type: E = Error

• Message class: EM - IS-U Migration

• Message number: 324

• Message text: Distributor import for migration object &1 only partially possible

What causes this issue?

Migration object &V1& is not entirely suitable for distributed import.
When importing this object a unique reconciliation key, which cannot be
used in parallel, is required for each import job.

System Response

INCLUDE ISU_VERARB OBJECT DOKU ID TX

How to fix this error?

Ensure that every import job uses a unique reconciliation key. This can
be done, for example, using the function module ISU_M_FIKEY DETERMINE.
In addition, the number of data objects per import file (package size)
for the distributed import should be as large as possible. This will
help to keep the number of reconciliation keys generated as low as
possible.
Alternatively, the import file can be manually split into individual
files (split migration file), and these can then be migrated using the
<ZH>Schedule Import Jobs</> function. However, no general error file or
error log will then be created.
