We are utilising this setup, and have the same senario where we have automatic transactions posting which require this default dimension (eg. intercompany posting). To ensure the automatic transactions will post, we have set the default to fixed value, however this means that if we populate this dimension field manually (and something which is different to the fixed default dimension), when the transaction is posted, it is then overridden with the fixed value. Any ideas on how we are to force the default dimension to populate for the automatic transactions, but still allow the dimension to be diferent when manually selected? Thanks! Lauren
