Select the Appropriate Record ID (A):
In the Salesforce Data Import Wizard, ensure that the Record ID field is correctly mapped. This field is required for updating existing records or ensuring data integrity.
Select "Upsert" Operation (C):
When using the Salesforce Data Loader, choose the "Upsert" operation. This allows the system to insert new records or update existing ones based on the Record ID or an external ID, ensuring that duplicates are avoided and data is accurately imported.
Steps to Resolve:
Check Field Mapping:
Verify that the Record ID field is mapped correctly in the import wizard or data loader.
Choose Upsert Operation:
If using the Data Loader, select the "Upsert" option to handle both insertions and updates.

When encountering governor limit errors on a particular job in NPSP, the consultant should decrease the batch size for that job. Here's why:
Batch Size:
Salesforce has strict governor limits to ensure efficient resource usage. When a batch job hits these limits, it often indicates that the batch size is too large.
Decreasing the batch size reduces the number of records processed in each batch execution, thereby minimizing the chances of hitting governor limits.
This approach helps in completing the job successfully without exceeding platform limits.
