Finally manage to solve it

Putting the data there was more or less correct like

update_post_meta( "$order_id", $field_rep, $row_no );
update_sub_field(array($field_key_rep, $sub_no, $field_key_sub), $trackno, "$order_id");

Think the main problem was when fetching the information and then doing it with the field names that would not work until the post was updated / saved. Using field_keys did on the other hand work.

if (have_rows($field_key_rep, $postID)) {

		$trackingNo = array();

		// loop through the rows of data
		while (have_rows($field_key_rep, $postID)):
			the_row();

			// Add to array
			$trackingNo[] = get_sub_field($field_key_sub);

		endwhile;
}
