Almost all of our items are Lot Numbered Assembly For very unique situation, we have to create a Credit Memo for some of the items. Of course, Netsuite request a Lot Number but we don't want to provide a lot number, we only want to credit the item, not the lot number How can I do that ?

Simon; In NetSuite, handling credit memos for lot-numbered assemblies without specifying a lot number can be managed by creating a separate item for credit memos. This allows you to credit the item without referencing a specific lot number. Here's a step-by-step guide: 1. Create a Non-Lot-Numbered Credit Memo Item: ◦ Go to Lists > Accounting > Items. ◦ Click on New Item. ◦ Choose the item type as Service or another non-inventory type. ◦ Set the necessary details for the credit memo item (e.g., name, description). 2. Create a Credit Memo: ◦ Go to Transactions > Customers > Enter Credit Memo. ◦ Choose the customer for whom you want to create a credit memo. ◦ Add the non-lot-numbered credit memo item to the credit memo. ◦ Enter the quantity and amount you wish to credit. 3. Complete the Credit Memo: ◦ Save and close the credit memo.

It makes a lot of sense.

No it does not make sense since the cost and income follow up of the ”real” assembly item will not work out of the box. This is another solution: Edit your credit memo form or create a separate form for this purpose Remove the sublist field ”inventory details” Create the credit memo. Set qty 0, rate 0 and then the amount you need to credit. Doing this, all income will be applied to the proper item.

It takes a lot of work to give a straightforward answer, depending on the situation. What you suggested will likely do the job; it's worth noting that it's more of a temporary fix and may impact the detailed reporting for inventory information on credit memos. I recommend testing both solutions in a sandbox environment first to see how they affect your system. It's better to catch any issues early on than to discover them six months later when they're harder to fix.
