3762054 - BOM migration fails with system error and memory dump— SAP S/4HANA Cloud Public Edition

• Error during migration of bill of material.
• "System error occurs when calling function module in target system" (DMC_RT_MSG 231)
• "System error (portion 0000000001, conversion object Z_BOM_3_M0M, at 134329)" (DMC_RT_MSG 39)
• "No more memory available to add rows to an interna (conversion object Z_BOM_3_M0M)" (DMC_RT_MSG 41)
• ABAP dump: SESSIONMEM_QUOTA_WARNING (limited amount of session memory remaining)
• ABAP dump: TSV_TNEW_PAGE_ALLOC_FAILED (no more memory available to add rows to an internal table)
• Issue occurs during import (migration), not during simulation
• Data import function module involved: DMC_MIG_MAT_BOM (package CS_MIG)

 SAP S/4HANA Cloud Public Edition

1. Open the Migration Cockpit app.
2. Open the project used for the Material BOM migration object.
3. Start the migration (import). Note that simulation completes without error, but the import fails.
4. To review details, open Monitoring in the project and check the failed import job.

The import processing for large BOMs loads all existing BOM items across alternatives into memory during the BOM update step, which can exceed the session memory quota and cause dumps (TSV_TNEW_PAGE_ALLOC_FAILED/SESSIONMEM_QUOTA_WARNING).

The issue will be fixed in CE2608.
