I am automatic on the basis of Shipment Number. Each time it will pick a shipment and run the Process

Hi @Nitin_Soni,
does it work if you pick “Get visible text” and while “indicating on screen” you mark the numbers from this particular column by dragging your cursor with a left click (just like when you normally select an area anywhere)?
Perhaps, or even better, you may apply the methods shown in the SAP automation training, where you operate on blocks:
Check e.g. the solutions starting from 12:27 minute of the movie: use basic recording - select “Copy” - click the first cell from the Shipment column). When you save it, it will generate “GetValue” activity in the Studio. Check if the row and column are marked in its selector with numbers. Use “Do While” loop to cycle, set up a counter for it with assign activity, and move your GetValue activity to the body of Do While. Change the Selector as shown in the movie. Perhaps the part from 14:48 on will be even more useful.

If you don’t get the right selector with “Copy” in Recording, you can correct it: go to the selector - Open in UiExplorer - Select (choose the field with the first shipment from the list). Check the selector with Validate and Highlight. If it is working, then copy the selector and replace the one you have in GetValue activity. It may help to put the whole thing in Attach Window activity.
Some advice here - replace the row number with a variable in the selector using the “Selector” field straight in “Properties Pane”, NOT by pressing “…” button next to it. Otherwise the change will not work.
Please refer to this thread to make things clear:

An example of some valid selector part that makes an automation iterate through SAP column is:
" /ctxtRV45A-MABNR[1," +counter.ToString+ “]’ />”
