3757882 - Issue with Product Validation BAdI Not Triggering During API-Based Material Creation

Validations via BAdI CMD_PRODUCT_VALIDATE work as expected when creating materials manually on the Manage Product Master Data app.

However, Validations fail to initiate when creating materials through OData API like API_PRODUCT_SRV.

1. Open the Manage Product Master Data app and create a material manually.
2. Observe that validations via BAdI CMD_PRODUCT_VALIDATE work as expected.
3. Use the OData API like API_PRODUCT_SRV to create a material.
4. Observe that validations fail to initiate.

The CMD_PRODUCT_VALIDATE BAdI is specifically designed for the "Manage Product Master Data" Fiori app and operates within the UI application layer rather than the API service layer.

When using API_PRODUCT_SRV, the system bypasses the UI-specific validation framework where your current BAdI implementation resides.

API services often use different processing paths that don't invoke UI-layer BAdIs to optimize performance. 

Implement the BD_CMD_PROD_DATA_API_CHECK BAdI which is officially designed to work for both the Manage Product Master Data app and the Unified Product Data API (including the API_PRODUCT_SRV).
