Ability to access item level EFF from Order Management algorithm

Hi,

We have a requirement to perform check item level EFF value. Use this value to perform service mapping from Order Management to AR to update one of the attribute value. Due to business requirement this value cannot be stored in OM so cannot use save extension to update header or line level in OM. Other reason is since service mapping is needed we cannot use save extension.

Is it possible to get PIM EFF using PVO in algorithm similar to save extension.

Thanks,

Vikas
