I have a number of PI Manual Logger tours that the user enters ore volumes and percentages by type. My expectation is that the user would enter a tonnage of material and an ore percentage by ore type and save the tour. What I have found in practice is that sometimes the user enters one and forgets to enter the other and saves the tour. This causes us problems in the AF Analysis calculations. So, here is my question. Is there a way in PI Manual Logger where we can make fields dependent on each other. If a user enters a material volume for gold can we not allow them to save the tour until they have also entered a percentage for gold? Please let me know.
