Retrieve Row Number

Hello.

Trying to automate GRPO Copy From multiple POs.

Need to be able to select multiple POs based on PO number. There is no issue storing and calling the PO numbers to find in the listing from Copy From button.

Intending to store the line number in @STORE fields for use with Click() in a macro call, but cannot seem to retrieve the values.

Is there something with the type of table (UID = 7) that requires a specific approach?

Any and all help appreciated.
