Establishing Robust Upsert Logic
To prevent duplicate account creation in Salesforce, we implemented a controlled upsert mechanism using Account Number as the primary external identifier. During synchronization, the integration first checks whether an account with the same Account Number already exists in Salesforce. If a match is found, the record is updated; if not, a new account record is created. This deterministic approach ensured idempotent processing, eliminated duplicate records, and maintained consistent and accurate account data across the ERP and CRM platforms.
