add subsidiary to the existing accounts using mass update

AI generated answer (using internal Slack threads):

To add a subsidiary to existing accounts using mass update, you can follow these steps: 1. First, you need to ensure that all transactions related to the accounts are deleted. This can be done using a mass delete or map reduce to delete transactions. 2. Once the transactions are removed, isolate the entities using the subsidiary. If the subsidiary to be deleted is not the main sub, you can update it by CSV or by script to delete only this subsidiary. If the subsidiary is the main sub, then completely delete the entity. 3. Next, isolate the accounts and update the subsidiaries on which it is defined by CSV or use a script to delete only the subsidiary to delete. 4. After ensuring that you have deleted absolutely everything on the subsidiaries, you can use a mass update script to update the subsidiaries. This script will take care of deleting only the subsidiaries specified in the script while keeping the others. Here is a sample script for mass update:

javascript
function each(recordType, id) {
    var record = nlapiLoadRecord(recordType, id);
    var subsidiaries = record.getFieldValues('subsidiary');
    var index = subsidiaries.indexOf('SUBSIDIARY_TO_DELETE');
    if (index > -1) {
        subsidiaries.splice(index, 1);
    }
    record.setFieldValues('subsidiary', subsidiaries);
    nlapiSubmitRecord(record);
}

Please replace 'SUBSIDIARY_TO_DELETE' with the internal ID of the subsidiary you want to delete. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
