Hi Ikhwan,

it's not possible to do this with the decimal function, because the max amount of numbers behind the dot is 8. You should probably handle this with a string field.

To calculate with the value of this string field in a microflow, you can use the parseDecimal option.

Hi Ikhwan Afiq,

Just check the Note under that Attribute,

The precision in the database is limited to 20 digits before and 8 digits after the decimal point.

So it should be less than 8 digits behind the decimal point.

Try to reduce the right side digit.

Hope It's helps you!!
