Installment Plan-- Payment Run

Question

Hi Friends,
by executing the Payment run for an Installment plan, comes the following error message.
Amount 34,10- EUR for document 9123456789 could not be broken down
Message no. >5251
Diagnosis
The amount specified is the clearing amount that is allotted to a collective bill or an installment plan with document number 9123456789. This amount is to be split over the items belonging to the collective bill or the installment plan by the clearing variant assigned to clearing type 20R and clearing category of the contract account.
The clearing cannot be posted for one of the following reasons:
You have not used a correct clearing variant for this business transaction.
No clearing variant could be determined.
Procedure
Check the relevant table settings for clearing control.
You must be able to split the amount over the items belonging to the collective bill or installment plan using the clearing variant. Therefore, you usually have to permit a partial clearing of these items.
The clearing variant must not use rules for automatic write-off of tolerance variances.
It is the 6th Installment plan of him, till now with Payment run- correct amount was deducted in Direct Debit and this is not the last Installment plan.
In clearing type 20R-Distribute Payment to Installment Plan-Usage 3 was used with check box for Incoming Payments was set.
1. I have no idea what caused the error message that was stated above.
2. As stated in the config for 20R-There is no payment, why did the system execute this Clearing type.
3. As it is direct debit the amount which was direct debited 34,10 is equal to IP.

Hi Lakshmi,
You need to check your customizing here:
>Contract Accounts Receivable and Payable
>Basic Functions
> Open Item Management
>Clearing Control
>Clearing Variants
  >Define Clearing Variants
   20S Collective Bill
>Define Clearing Types
  R 20S Distribute payment to collective bill
  "You cannot change the clearing types delivered by SAP."
>Define Specifications for Clearing Types
  >Define Defaults for Collective Invoice/Installment Plan/Summarization
   20S Distribute payment to collective bill 20S
   "Special Features
    The clearing variant defined for these clearing types must
    guarantee that the clearing amount in question can be distributed
    in full to the related dependent single items. The variant may not
    use any rules for automatically writing off tolerance discrepancies.
    Otherwise, processing will be terminated. ..."
Please make sure above customizing is maintained.
I hope this helps.
