# AIAB : AUC settlement multiple line item

Hi

We are creating settlement rule for auc , having multiple line item . Initial execution of AIAB, shows the line items as below.

I select all of these line items and then in the next screen, I provide the below.

Then I come back and execute the settlement.

I get the below error. Just wanted to know, how AIAB relates each line item in AUC to the amounts entered in the "Maintain settlement rule screen"

As I selected all the line item of AUC, I thought the entire amount is 3120, which I can distribute among two items. Please let me know, that, if there are three line items should I always enter 3 items in the settlement rule section? What if, I wanted to maintain 4 receivers in total for the 3 line items.

Please let me know.

Hi Swastik,

System works the same with both types. The different behavior is because of maths. If you think about the different nature of percentage based calculation and value based calculation, you will notice why it will work with the percentage rates, but cannot work with an amount based settlement rule.

For example if you define settlement rule with two receivers that get 30% and 70%.

In this case system will calculate 30% and 70% for each of your items separately(!). Then afterwards the values are totaled up for each of the receivers.

The result will be the same as when calculating 30% and 70% for the accumulated amount of all three items at once. So you do not notice the difference.

No matter how many items you have, settlement will always split 100% percent of the total amount to the receiving assets (30% + 70%). Of course this will not exceed the total amount for each item and you will not get any error because it will always be exactely 100%.

However, if you use amount based settlement of 2.000 and 1.000 then system will try to settle 3.000 for each(!) item. If you assign this settlement rule to 3 items, the total amount to settle will be 9.000. This is much more than 100%.
