Append to XML remains greyed out

Question

Hi folks,
I am using MII 15.0 SP2 Patch 8. I created a new transaction having a xML transcation variable called "test" defined as you cans ee in below screenshot. It is a plain XML having a root node called options.
Thereafter I created a new transaction adn placed an assignment block there. I treid to use append XML link type to extend my transaction variable. Unfortunately, when trying to append some new xml to test{/OPTIONS}, append XML functions remain greyed out...see screenshot below
Any idea why that happens? Thanks for your help!

Hi Anuji, thanks for your answer, u r right. But what if I do not want to choose some value from menue? My plan was to define a new XML segment as string in Expression Editor and append it to my XML. Does that mean this is not possible?
I somehow need to build a multiline XML looking like this:
<option>
<item><text>content...</text></item>
<item><text>content...</text></item>
<item><text>content...</text></item>
<option>
Content should define a multiline "where clause". Eventually, I want to map resulting XML to options input section of RFC_READ_TABLE to query data from ERP using JCO connector.
What's a suitable approach to get there?
