About Cost Apportionment Equivalence Number Decimal places

Hello everybody.

I am maintaining the cost apprtionment structure in the material master for a co-product but I do not have enough significant figures to perform de expected distribution. Currently, the equivalence number field MAKZ-ZIFFR is defined as data type DEC, length 3, 0 decimal places.

Does anyone knows if there is a way of to add more segnificant figures to this field.
