OData API for material management returns slow response time

We’re experiencing significant performance degradation when creating materials in bulk via the OData API (I_ProductTP service). Creating 500 materials takes over 45 minutes, which is unacceptable for our daily integration jobs.

Current implementation sends individual POST requests:


POST /sap/opu/odata/sap/API_PRODUCT_SRV/A_Product
Content-Type: application/json
{
  "Product": "MAT-12345",
  "ProductType": "FERT"
}

The batch processing strategy doesn’t seem optimal, and I suspect the underlying CDS views might be contributing to the delay. We’re on S/4HANA 2020 FPS02. Has anyone dealt with bulk material creation performance issues? What’s the recommended approach for optimizing OData batch operations when dealing with large volumes?

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

1. Bulk Operation Optimization Implement OData $batch with optimal sizing:


POST /sap/opu/odata/sap/API_PRODUCT_SRV/$batch
Content-Type: multipart/mixed; boundary=batch_001

--batch_001
Content-Type: application/http

POST A_Product HTTP/1.1
{"Product": "MAT-001", "ProductType": "FERT"}

Use 50-75 materials per batch request. This balances transaction size with commit frequency. Larger batches risk timeouts and make error recovery harder.

2. CDS View Performance The I_ProductTP view is comprehensive but heavy. Use a staged approach:

  • Stage 1: Create basic material (Product, ProductType, BaseUnit) via I_ProductTP
  • Stage 2: Extend to plants using I_ProductPlantBasic
  • Stage 3: Add sales org data via I_ProductSalesDelivery

This prevents the CDS view from joining 15+ tables during initial creation. Our benchmarks show 60% improvement with staged creation.

3. Batch Processing Strategy Implement parallel processing with proper error handling:

  • Split your 500 materials into 10 batches of 50
  • Process 2-3 batches in parallel (test your system’s capacity)
  • Implement retry logic for failed batches
  • Log each batch result separately for troubleshooting

Additional optimizations:

  • Disable number range buffering check (SNUM_BUFFERING) if using external numbering
  • Schedule during off-peak hours to avoid lock contention
  • Monitor table MARA locks using SM12 during processing
  • Consider using background job processing (transaction SM37) instead of real-time API calls for very large volumes

With these changes, you should achieve sub-10 minute processing for 500 materials. I’ve implemented this pattern across 4 S/4HANA implementations with consistent results. The key is reducing the CDS view complexity per operation and optimizing batch sizes based on your specific system capacity.

Individual POST requests are definitely your bottleneck. You should be using OData batch requests with the $batch endpoint. This allows you to bundle multiple operations into a single HTTP request, drastically reducing network overhead and connection time. The API_PRODUCT_SRV supports batch operations natively.

I had similar issues last year. Beyond batch requests, check if you’re triggering unnecessary validations or workflows during creation. We disabled certain custom validations during bulk loads and ran them as a separate post-processing step. Also, the CDS view I_ProductTP can be slow if you’re including too many associated entities in your payload. Strip down to only required fields initially, then update with additional details if needed. Our processing time dropped from 40 minutes to under 8 minutes for 500 materials.

Thanks for the suggestions. I implemented batch requests but still seeing around 25 minutes for 500 materials. The CDS view optimization point is interesting - we are including plant data and sales org assignments in the initial POST. Would it be better to use a two-stage approach?

Yes, two-stage is recommended. Create the material master first with minimal data, then use separate calls to extend to plants and sales orgs. The I_ProductTP view joins multiple tables, and when you include plant/sales data upfront, it triggers additional validations and table locks. Also check your batch size - don’t send all 500 in one batch. Optimal is usually 50-100 materials per batch request to balance throughput with transaction size.

Another factor: check if custom BAdIs or user exits are active in your material creation process. Use transaction SE19 to review active BAdI implementations for material master. We discovered a custom validation BAdI that was making database calls for each material, adding 3-4 seconds per record. Disabling it during bulk loads and running validation separately reduced our total time significantly.
