Thank you Baithi for the reply. The PDF is helpful in case i want to find the difference between current date and one of the field dates! I want a formula in BRF+ for a constant date and it may not be the current date or system date!
Example, say i want to see how many journal entries are posted on 31 march or April 1, then, is there a way to find this out? I remember reading about expression 'CONSTANT_DT_20160101_EXP' But now i am not sure if this is correct.
