What does the error message "FormCompetency does not support operation POST" mean?

[former_member25038]

I want to update "FormCompetency" entity by using Integration Center(import csv).

When I tried to update "FormCompetency" entity by using Integration Center(import csv), I got the error message "FormCompetency does not support operation POST".

Does this error message mean that FormCompetency can't update by using Integration Center(import csv)?

(I know this is possible using the ODATA API. I referred to the following blog.

- https://blogs.sap.com/2018/11/25/how-can-we-run-end-end-performance-appraisal-process-using-odata-ap...

The case of this blog uses ODATA API, but I want to use Integration Center(import csv) instead of ODATA API.

ODATA API cannot be used due to our circumstances.)
