Thanks for joining the Community and getting involved with this thread, Grimlock.

The invoice or transaction date you select needs to be set after the date you set up in your As of date field for the product or service. This is because transactions using an Inventory Item can't be edited if its Inventory Start Date occurs after a transaction was made.

For example, if your inventory date is set to October 10, 2024, you'll want to enter a date that comes after that one when creating transactions.

If you're already trying to enter a date that comes after your inventory start date, but aren't able to save it, you'll want to perform the browser and system requirement troubleshooting shared in Erika_K's post.

In the event your error continues displaying after performing each of our recommended troubleshooting steps, I'd recommend getting in touch with our Customer Care team. They'll be able to pull up the account in a secure environment, conduct further research with you, and create an investigation ticket if necessary.

They can be reached while you're signed in.

Here's how:

1. Use the Help (?) icon.
2. Click Contact Us.
3. Enter a description of your situation in the What can we help you with? field, then hit Let's talk.
4. Select Start messaging or Get a call.
   
   

Be sure to review their support hours so you'll know when agents are available.

If there's any additional questions, I'm just a post away. Have a great Friday!
