Resolving NetSuite Inventory Assignment Errors

When working with NetSuite to retrieve inventory detail subrecords from transactions, you may encounter items that do not require inventory assignment. Despite not assigning inventory, simply fetching existing inventory details can trigger an error message: “You Cannot Assign Inventory details for this item.”

Understanding the Error:

This error occurs because NetSuite’s validation process checks for inventory assignment even when you are only retrieving details. To bypass this issue, you can use the Record.hasSublistSubrecord(options) method.

Solution:

Using Record.hasSublistSubrecord(options)

The Record.hasSublistSubrecord(options) method allows you to check if a sublist subrecord exists without triggering the inventory assignment validation. Here’s how you can implement this solution:

Check for Sublist Subrecord: Before attempting to fetch inventory details, use the Record.hasSublistSubrecord(options) method to verify if the sublist subrecord exists.

Fetch Inventory Details: If the sublist subrecord exists, proceed to fetch the inventory details without triggering the error.

Implementation Example:

Here’s a sample code snippet demonstrating the use of Record.hasSublistSubrecord(options):

var transactionRecord = context.newRecord;
        var sublistId = 'item';
        var lineCount = transactionRecord.getLineCount({ sublistId: sublistId });


        for (var i = 0; i < lineCount; i++) {
            if (transactionRecord.hasSublistSubrecord({
                sublistId: sublistId,
                fieldId: 'inventorydetail',
                line: i
            })) {
                var inventoryDetail = transactionRecord.getSublistSubrecord({
                    sublistId: sublistId,
                    fieldId: 'inventorydetail',
                    line: i
                });
                // Process inventory details
                log.debug('Inventory Detail', inventoryDetail);
            } else {
                log.debug('No Inventory Detail', 'Line ' + i + ' does not have inventory details assigned.');
            }
        }

Conclusion:

By using the Record.hasSublistSubrecord(options) method, you can effectively bypass the inventory assignment validation error in NetSuite. This approach ensures smooth retrieval of inventory details without unnecessary interruptions.
