Oracle primavera unifier

Hi! i need you help!

I have to create a CBS code on a specific shell using REST API.

I was able to correctly login and obtain the Bearer token.

then we I create the API call I write like this:

https://eu1.unifier.oraclecloud.com/CUSTOMER/test/ws/rest/service/v1/cost/cbs/list/?project_number=6964

and in the bodyraw Jason I put this..

{
"data": [
{
"code": "RTL",
"description": "Creating Cost Code using REST webservice",
"item": "Rettifica Termine Lavori",
"uResProgressAmount": 10,
"status": "Active",

}]}

i got 200OK but in the system anything happens and, if i check on body message i found status 602
