Is there any BAPI to close service order requests?

Hi,

In my scenario, the business creates a service order request using transaction iw52. A field technician then goes to the customer's site to fix the problem. After the problem is fixed, the technician would run a custom application to close the service order request.

I am still developing the custom application. However, I have not been able to find a BAPI that would help me close the service order request. Can someone please help me find either an exact BAPI or the closest one?

Thank you in advance for your help.
