OData vs. DMF vs. Dual-Write - Choosing the Right Approach:
"Your project involves integrating customer and order data from a web-based application to D365 F&O. The integration must create records in real-time and also synchronize data between the systems. What integration technologies would you use (OData/REST, DMF, dual-write, etc.) for different needs (e.g., real-time vs. bulk)? How does each choice impact how you handle number sequence assignments for new records?"
Interviewer guidance: A well-rounded answer will differentiate scenarios:
-
Real-time creation (e.g., new orders at checkout might use OData or a custom service calling a data entity, letting F&O auto-generate the Sales Order ID to avoid collisions).
-
High-volume or periodic loads (e.g., bulk imports or migrations using DMF with auto-numbering for efficiency and reliability).
-
Dual-write for ongoing synchronization of master data (with careful planning to avoid number conflicts, possibly designating one side for number generation or using distinct formats).
Look for reasoning on each approach's suitability (e.g., OData's real-time but with potential throttling vs DMF's batch mode for large volumes) and how numbering is handled in each method.
