I have items that are related to each other and depending on which fields are updated then the information on the related items must be updated also. The related items don't need to be completely in sync, just certain fields. After an item has been modified I check to see what has changed and then store in a temporary record the field no. that changed and the new field value. From this how can I update the correct field value in the related item record bearing in mind I just know the field no. that needs to change?
