Maximum available Chek limit that can be used by a customer. This is not a periodic limit. This is the total amount which customer can use anytime. Available limit decreases as customer uses it and increases as customer pays it back.
Example: If limit is $5000 and customer uses Cheks equal to $2000 then balance usable Chek limit is $3000. If customer pays back $1500 then balance usable limit will increase to $4500.
