Updating Parent for Existing Assets
Overview
When importing data repeatedly, existing records may require updates. One common case is moving an Asset between parents when its status changes.
Scenario
Initial Import:
Client-000001 → Parent: Active
Later Import: Client-000001 → Active = FALSE
Expected Result: Client-000001 → moved to Inactive
Example Mutator
return function mutate(sourceData, columnNames, rowObject, connectionData, createError)
{
const [raw] = sourceData;
if (raw == null || raw === "") {
createError("Active value is missing");
return [];
}
const val = (raw + "").trim().toUpperCase();
if (val === "TRUE") {
return ["Active"];
}
else if (val === "FALSE") {
return ["Inactive"];
}
else {
createError("Invalid Active value: " + raw);
return null;
}
}Important Considerations
- The connector must allow updates (not insert-only)
- Parent field must always be included in mapping
Result
- Existing assets are updated correctly
- Parent changes are reflected automatically
