Personas 2.3: Some recorded script is not editable, are they really needed?

Hi Personas 2.3 experts,

I have a general qustion - when manipulating some SAP controls, one can record some script and modify it for his own use. However, the recorded script often include some items that are not editable. When modifying such recorded scripts, should these non-editable items be kept or removed? Why?

Below is a screen shot of such as recorded script:

Can anyone explain why we need "SelectRows" and "SetCurrent" items in the script? Thanks.
