Bill of Materials synchronization fails due to inconsistent lifecycle states

We’re experiencing critical BOM synchronization failures in our SAP PLM 2020 environment. The sync jobs fail when material master data is in inconsistent lifecycle states across different BOM levels. The issue particularly affects materials transitioning between Released and Obsolete states.

When the synchronization runs, we get errors like:


Error: BOM_SYNC_001 - Material master lifecycle mismatch
Material: 100234-A (Status: Obsolete)
BOM Parent: 200456-B (Status: Released)
Sync terminated at line 2847

This impacts our product releases severely - engineering changes can’t propagate to production BOMs, causing delays of 3-5 days per change cycle. The material master alignment seems correct when we check manually, but the BOM synchronization logic doesn’t recognize it. Has anyone encountered similar lifecycle management process impacts in their PLM-ERP integration?

Let me provide a comprehensive solution addressing all three focus areas:

Material Master Attribute Alignment: First, ensure your material master lifecycle states are properly synchronized across all systems. Execute transaction MM03 and verify that fields MSTAE (cross-plant material status) and MMSTA (plant-specific status) are consistent. The BOM sync reads from both, and mismatches cause failures. Implement a pre-sync validation check:

SELECT mara~matnr mara~lvorm marc~mmsta
INTO TABLE lt_validation
FROM mara INNER JOIN marc
WHERE mara~matnr IN s_matnr
AND (mara~lvorm <> '' OR marc~mmsta IN ('98','99')).

This identifies materials with deletion flags or obsolete statuses before sync runs.

BOM Synchronization Logic: The core issue is the timing window between material master updates and BOM sync execution. Modify your sync job configuration in transaction CMOD (Project: SAPLCSDI or similar) to implement these changes:

  1. Add a 5-minute buffer after material master commits using function module ‘ENQUEUE_WAIT’
  2. Implement lifecycle state caching to avoid reading inconsistent intermediate states
  3. Configure the sync to process BOMs in dependency order (leaf components first, then parent assemblies)

In your BOM sync configuration (transaction CS20), set these parameters:

  • Check indicator: ‘Lifecycle validation’ = Warning only (not Error)
  • Processing mode: ‘Sequential with dependency resolution’
  • Retry logic: 3 attempts with 2-minute intervals

Lifecycle Management Process Impact: To prevent future issues, implement an event-driven architecture:

  1. Create a change document object for material master lifecycle changes (transaction SCDO)
  2. Implement BAdI ‘BADI_MATERIAL_CHECK’ to trigger sync events only after successful commits
  3. Use workflow event linkage (transaction SWETYPV) to connect material master changes to BOM sync jobs

The workflow should follow this sequence:

  • Change master approval (status → Released)
  • Material master update with commit work
  • Wait for database commit confirmation (check table CDHDR for change document creation)
  • Trigger BOM sync via event ‘MATERIAL_CHANGED’
  • Monitor via custom Z-table with fields: MATNR, CHANGE_TIMESTAMP, SYNC_TIMESTAMP, STATUS

Critical Configuration Steps:

  1. Transaction SPRO → Logistics General → Material Master → Basic Settings → Material Statuses → Define lifecycle transition rules (allow Released→Obsolete transitions with warning)
  2. Transaction SE37 → Function module ‘CSAP_MAT_BOM_MAINTAIN’ → Add custom wrapper to include lifecycle validation
  3. Create monitoring report using transaction SM36 to schedule hourly validation checks

Validation Query:

SELECT b.matnr, b.stlnr, m.mstae, c.timestamp
FROM mast b
JOIN mara m ON b.matnr = m.matnr
JOIN cdhdr c ON m.matnr = c.objectid
WHERE c.change_ind = 'U'
AND c.udate >= sy-datum - 1
ORDER BY c.udate DESC;

This solution addresses the material master alignment, fixes the synchronization logic timing issues, and minimizes lifecycle management process disruptions. The event-driven approach eliminates the 3-5 day delays you’re experiencing. Test thoroughly in your development environment first, especially the lifecycle transition rules, as they impact compliance processes.


This draft is based on general SAP PLM knowledge. It has not been verified against your specific version and environment. Practitioners: verify the steps and share your experience below.

I’ve seen this before. The issue is likely in how SAP PLM Data Connector handles lifecycle state transitions during the sync window. Check your BOM synchronization job configuration - specifically the lifecycle validation rules. The system might be checking parent-child lifecycle compatibility too strictly. Review table MARA field LVORM (deletion flag) and ensure it’s properly mapped in your sync configuration.

Adding to what Raj mentioned - we had a similar situation last year. The problem was that our BOM sync job was running with a 15-minute schedule, but material master updates were batch-processed every 30 minutes. This created a timing window where the sync would read inconsistent states. We solved it by implementing event-driven triggers instead of scheduled jobs. Also check if you have custom ABAP code in any BOM-related user exits that might be enforcing additional lifecycle validations beyond the standard SAP logic.

Quick question - are you using variant BOMs or standard BOMs? And what’s your change master integration setup? In our implementation, we discovered that the lifecycle state validation was happening at the wrong point in the process. The sync was checking states before the change master workflow completed, which caused false failures. We had to adjust the sequence: change master approval → material master update → wait for commit → then trigger BOM sync. The wait-for-commit step was crucial.

Thanks for the insights. Klaus - we’re using standard BOMs with some variants for product families. Our change masters are integrated but I think you’ve identified the issue. The sync is definitely running before the material master commits are complete. Sarah’s point about event-driven triggers makes sense too. Let me check our current job scheduling and the commit timing. Do you have any recommendations for monitoring tools to track the actual commit timestamps versus sync execution times?

For monitoring, look into transaction SM37 for background job logs and ST22 for ABAP dumps. But more importantly, check transaction BD87 for IDoc processing if you’re using ALE/IDoc for the sync. The real-time monitoring there will show you exactly where the timing gaps are. We use custom Z-table logging to track material master state changes with timestamps, then correlate those with BOM sync job execution times from SM37. This gave us the evidence we needed to prove the timing issue to our basis team.

Confirmed this resolves BOM sync failures—aligning MSTAE and MMSTA via MM03 with the pre-sync ABAP validation against MARA/MARC eliminated our inconsistency errors immediately.

I want to add something about the lifecycle validation logic itself. In SAP PLM 2020, there’s a specific configuration in SPRO under Cross-Application Components → Classification System → Master Data where you can define allowed lifecycle state combinations for BOM components. By default, it’s quite restrictive. We loosened it to allow Released parents with Obsolete children (with warnings instead of hard failures), which solved 80% of our sync issues. Just make sure your business process can handle that flexibility from a compliance perspective.
