We have approximately 460 Rate Matrices configured for our 7.5.3 (yeah i know it's old) version of clarity. Accounting just noticed that each of these Rate Matrices are configured with a From Date of 1/1/90 and a To Date of 12/31/2009. Obviously that 'To Date' is now in the past and is worrying me. My question is, will we have to change all of these Rate Matrices 'To Date' to some time in the future to prevent any problems and if so is there a mass way to change these? Much thanks for any help.
