Converting the sub-system balance into the numeric

Content

Hello,

We are required to convert the sub-system balance into a numeric format. As it is required to be used in the ABS function in the attributes. The sub-system balance is not numeric so using the same attribute in the calculation, an error of Parameter-1 is occurring.

Kindly help to resolve the same or if there is any way around to achieve the same will be helpful.
