Character length on RTAM in DBA Instructions max at 99999.9999

Hi, we have a PDBA that requires the Amount (RTAM) to be $100,000 but the system limits the characters in this field to 99999.9999. How have others gotten around this issue? Our PDBA set up is pretty simple. We currently have $50,000 life insurance coverage and the rate on that coverage is $6.40. We have a PDBA that holds the coverage amount of $50,000 and a second PDBA that holds the rate and uses the first PDBA as the Basis of Calculation. We want to simply increase the coverage amount to $100,000 but the system does not accept that amount. It will revert it to 99999.9999.
