A/P Down payment invoice Problem

Question

Hi all,
I have the ff. scenario
1.     Create PO
2.     Create A/P DP invoice(20%) against this PO
3.     Create outgoing payment against A/P DP invoice of 20%
4.     Create A/P DP invoice(30%) against this PO
5.     Create outgoing payment against A/P DP invoice of 30%
6.     Create A/P DP invoice(60%) against this PO
7.     Create outgoing payment against A/P DP invoice of 60%
8.     Create a regular A/P invoice against the 3 DP
Problem 1. We have exceeded our payment against the PO w/c in this case is 110%, but SBO allowed to post these Down payments. How can we prevent overpayment base on a specific PO?
Problem 2. Since we have overpayment what we should do on 10% overpayment?
Please help.

Hi Fidel,
Sorry for the late post, quite a busy day for me today.
edit - start
Errrrr, line 12 actually should be IF @iBaseType (less-than-symbol)(greater-than-symbol) 22
Why this forum remove those 2 symbols whenever I write them? Anyway, you should understand it, I mean "IF @iBaseType is not equat to 22" in SQL script. Just curious why SDN automatically remove whenever those 2 symbols adjacent to each other, weird...
And the same thing apply to line 25, should be AND TargetType (less-than-symbol)(greater-than-symbol) 19
edit - end
IF @object_type='204'AND @transaction_type='A' -- 204 is object type for A/P DP Invoice
  BEGIN
    DECLARE @iBaseType AS INT               -- To contain base document type of A/P DP Invoice
    DECLARE @lDpmPrcnt AS DECIMAL(18,2) -- To contain sum of DP% related to the based PO
     SELECT @iBaseType=BaseType
     FROM ODPO T0
     INNER JOIN DPO1 T1 ON T0.DocEntry=T1.DocEntry
          WHERE T1.DocEntry=@list_of_cols_val_tab_del
     IF @iBaseType<>22          -- Make sure in order to create DP, a PO is required (PO object type is 22)
       BEGIN
          SET @error=-1
          SET @error_message='PO required in order to create purchase down payment'
       END
     ELSE
       BEGIN
          SELECT @lDpmPrcnt=SUM(DpmPrcnt)
          FROM ODPO T0
          INNER JOIN DPO1 T1 ON T0.DocEntry=T1.DocEntry
               WHERE BaseType=22
               AND BaseEntry=(SELECT BaseEntry FROM DPO1 WHERE DocEntry=@list_of_cols_val_tab_del)
               -- Line above is to select all DP related to base PO
               AND TargetType<>19
               -- Line above is to make sure DP that already reversed using A/P Credit Memo is excluded
               AND LineNum=0
               -- Make sure to add line above due to facts that DP% located in document header
               -- and since we join ODPO with DPO1,
               -- if line above doesn't exist, the sum of DP% will duplicated accordingly to number of line items in document
          IF @lDpmPrcnt>100
            BEGIN
               SET @error=-1
               SET @error_message='Down payment percentage already exceeded 100% of PO'
            END
       END
  END
Inform me if you have any inquiry or problem regarding this SP.
