AO Planning - Member Recognition

I'm using input ready bex query in AO for planning.

In AO 2.1, If I provide a partial value for any info object characteristic and hit "Enter" key, it prompted with a list of master data.

In AO 2.2, If I provide a partial value for any info object characteristic and hit "Enter" key, it shows a warning message saying invalid value.

In order to find a solution I tried below options, but no luck

1. Searched in AO 2.2 User Guide

2. Searched on service.sap.com for topics like AO planning, AO member selector, AO input value help

3. Went through certain SAP notes, SCN discussions, wiki pages and blogs.

Thanks,

Hardik
