Issue with rounding need to cancel it

R12.1.3

Hello Folks,

I have a rounding issue with Custom SIT (Overtime Request) with segment which required

and have sql statement as below

SELECT ROUND(ROUND(:$FLEX$.XX_GROSS_SAL_V6 / 30,2)/8,2) FROM DUAL

And value set with type number and precision 2

And I change it to be

SELECT TRUNC(:$FLEX$.XX_GROSS_SAL_V6 / 30)/8),5) FROM DUAL

And change the value set to be number too and precision 5

But it don’t work and show error that this required field don’t have value

 (Segment required but calculated automatically not entered by the user)

And inputs folks?

Thanks
