Suppose the following scenario:
1) We create a request for an advance or an expense report in the system and the same is not submitted for approval. Beginning and end dates are, respectively, 01/01/2010 and 02/01/2010.
2) We create another request for an advance with the same start and end dates (01/01/2010 and 01/02/2010) and we record it but we don't sent for approval as well. A message of warning it is generated but we managed to record it.
Message Number: 56146
Trip data for the period from 01/01/2010 to 02/01/2010 already exists.
Is there a possibility that rather than sending a warning system to give an error message?
Thanks in advance and kindly regards,
