# Reopens a complete or cancelled job operation, setting it back to Ready.

`POST /api/jobs/{jobId}/items-to-make/{itemToMakeId}/operations/{operationId}/reopen`

## Request

- Base URL: `https://api.fulcrumpro.com`
- URL: `https://api.fulcrumpro.com/api/jobs/{jobId}/items-to-make/{itemToMakeId}/operations/{operationId}/reopen`
- Auth: none declared

Resets the operation's quantity made to zero (an outside-processing operation keeps what its purchase
orders received), sets downstream Ready operations back to Pending, and moves the job to In Progress.
When the item was complete, the finished goods this job received for it are taken back out of inventory.
The revert is all or nothing: when later inventory activity on the received lots blocks it, every receipt
stays. Receipts through outside-processing purchase orders always stay, and reopening one chain of a
split operation keeps all of the item's receipts. Materials picked for the operation stay
picked; completing it again does not pick them a second time. Reopening an operation that is already
Ready changes nothing, so a request that may not have landed can be safely resent.
