recently during testing of some logic for me it was necessary to assign some random values to table VendorPart in Acumatica. In order to achieve it, I've created such a script:
update VendorPart set NetPrice = (ABS(CHECKSUM(NEWID()))% 3000.25 + 1.1 + 1), ListPrice= (ABS(CHECKSUM(NEWID()))% 3000.25 + 1.1 + 1) where NetPrice = 0 and ListPrice = 0
of course such a query will not satisfy all requirements for random numbers generator, but in scope of my business scenario it was better then assign the same value to both columns.
If you want to have some diversity in digits for your values, use NEWID function for assigning values.
