how can i target po lines to delete using a mass update?

AI generated answer (using internal Slack threads):

To target Purchase Order (PO) lines for deletion using a mass update, you can use a SuiteScript similar to the one used for deleting addresses in the first thread. Here's a modified version of that script:

javascript
// Delete PO Lines
var Rpo = record.load({type: record.Type.PURCHASE_ORDER, id: _poid, isDynamic: true});
var line_count = Rpo.getLineCount({sublistId: 'item'}) - 1;
var _changed = false;

for (kk=line_count;kk>-1;--kk) {    
    Rpo.selectLine({sublistId: 'item',line: kk});
    Rpo.removeLine({sublistId: 'item',line: kk,ignoreRecalc: true});
    _changed = true;
} 

if (_changed == true)
    Rpo.save();

This script loads the Purchase Order record, gets the count of line items, and then loops through each line item in reverse order, removing each line. If any lines were removed, it saves the record. Please note that this script will delete all lines from the Purchase Order. If you want to delete specific lines, you will need to add a condition inside the loop to check for the lines 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. ******
