Cannot update availability, location via edit resource function

Hi Folks,

As part of our original PPM rollout, PPM resources (or Business Partners) were created using HR integration. We have since changed the process to create BP's directly in PPM using the Create Resource or Edit Resource (webdynpro web UI) function.

The issue I am facing is when I try to update the status, availability or location for a resource/BP that was created using HR integration it does not allow me to do so. No issue for resource created directly in PPM. I can do this without any issues using transaction RPM_EMPDATA. Any ideas as to why I cannot perform the same function using the webdynpro UI which is what end users will be using.

Here's screenshot showing the create button disabled. I see the same behavior in the location and availability tabs as well where the buttons are disabled.

Thanks,

Lashan
