Error while work order creation for CTO/ATO item through Sales Order

Summary:

Hi All,

Getting following error - 'The item you provided, 300000038744903, isn't set up for work order creation. Try again after the following item attribute values are changed: Set Transactable to Yes.'

We have done the CTO configuration, and when sales order is submitted through order management, Supply Order Details gives the above error. We have also defaulted the CTO Item Template in Item Class and all the item attributes are set correctly in Item template but still we are facing this issue.

Following setups are done-

1. Created component items
2. Created structure within the Option Class item and assigned above item in it (Also enabled Optional, where needed for the components)
