質問 # 88
A business currently has a process to manually upload orders from its external Order Management System (OMS) into Salesforce.
This is a labor intensive process since accounts must be exported out of Salesforce to get the IDs. The upload file must be updated with the correct account IDs to relate the orders to the corresponding accounts.
Which two recommendations should make this process more efficient?
Choose 2 answers

A. Identify unique fields on Order and Account and set them as External IDs.
B. Use the insert wizard in the Data Loader to import the data.
C. Use the upsert wizard in the Data Loader to import the data.
D. Ensure the data in the file is sorted by the order ID.

正解：A、C

解説：
The two recommendations that should make this process more efficient are to identify unique fields on Order and Account and set them as External IDs, and to use the upsert wizard in the Data Loader to import the data. External IDs are custom fields that have the External ID attribute enabled, which allows the developer to use them as a unique identifier for the records. By setting the unique fields on Order and Account as External IDs, the developer can avoid the need to export and update the Account IDs, and instead use the External IDs to relate the Orders to the Accounts. The upsert wizard in the Data Loader is a tool that allows the developer to insert or update records based on the External ID or the Salesforce ID. By using the upsert wizard, the developer can import the data in one operation, and avoid creating duplicate records. Using the insert wizard in the Data Loader to import the data will not make the process more efficient, as it will require the developer to export and update the Account IDs, and also handle the duplicate records. Ensuring the data in the file is sorted by the order ID will not make the process more efficient, as it will not affect the relationship between the Orders and the Accounts, or the insertion or update of the records.
