Dynamic selectors in SAP

Hello Community,

i really have a problem with input fields in SAP, because those fields have dynamic selectors and a very small amount of possible items:

I already use the * option within the first selected items, but it is not enough.

Items, e.g. parentclass, are not a good option to choose, because it is not different to any other input fields within the SAP window.

Do you have an idea, how i can stabilize my selectors or how to use an anchor for those specific fields?

Best regards
