I am creating a Transfer Order in NetSuite via the SOAP API and I'm managing to do so just fine, without problems. I am then passing a second SOAP API call to create an item fulfilment record, basically the 3 serial numbers I want to use to fulfill the transfer order with. When I try to create the item fulfilment record, I am immediately getting this error: "Adding new line to sublist item is not allowed." What could be the problem please, could you guide me?

AI generated answer (using internal Slack threads):

Based on the conversations, the error "Adding new line to sublist item is not allowed" when creating an item fulfillment record via the SOAP API could be due to several reasons: 1. Incorrect Line Mapping: The 'orderline' field on the item fulfillment should match the 'line' field on the sales order or the transfer order if the fulfillment is for a transfer order. If you're using a tool like Celigo, you can map any field using jsonpaths. For example, orderline would be

item[*].orderline

. 2. Invalid Sublist Operation: The error message "You have attempted an invalid sublist or line item operation" suggests that there might be an issue with the way you're handling sublists in your SOAP API call. Make sure you're not trying to add an item to a sublist in a way that's not allowed in item fulfillments. 3. User Event Script: The error could also be due to a user event script that's interfering with the creation of the item fulfillment record. Check any scripts that are deployed on your item fulfillment for potential issues. 4. Incorrect Field Values: Make sure all the field values you're setting in your SOAP API call are valid. For example, setting an incorrect status internal ID could cause an error. 5. Missing Line Items: The error "You must have at least one valid line item for this transaction" suggests that your item fulfillment record might not have any valid line items. Make sure you're correctly adding line items to your item fulfillment record in your SOAP API call. Remember to follow the same order of operations as you would in the NetSuite UI when working in dynamic mode. For example, you wouldn't remove the subrecord in the UI, so you shouldn't in dynamic mode either. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
