REST api to reverse project cost

Summary

Unable to reverse project cost using REST

Content

I am trying to use REST api to reverse an existing project cost transaction.

From the documentation I guess that it is supposed to work:

https://docs.oracle.com/en/cloud/saas/project-management/21b/fapap/op-projectcosts-projectcostsuniqid-x-operations-0.html

According to the above mentionned documentation I try to do a POST to:

https://xxxx.oraclecloud.com:443/fscmRestApi/resources/11.13.18.05/projectCosts/1640001/Adjustments

And using a body like:

{

"name":"adjustProjectCosts",

"parameters":

[

              {"AdjustmentType": "Reverse"}

]

}

 

But it is not working. Any ideas or working examples would be very appreciated.
