Online update in FM, SAP 6.0

Question

Hi people,
We are using online update of payment in SAP 6.0 as default for new customers. However i can't find the right combination of commitment item to address the following business process.
I need to post travel expenses and travel advances that are payed through FI. These document are actually invoices with employee acting as a vendor.
travel advance looks like
31 vendor (CI 60)
40 advance
travel expense looks like
31 vendor (CI 60)
40 expenses (CI 30)
50 clearing of advance previously posted.
CI - commitment item type
Problem occurs when we try to clear amounts on advance account and we produce exchange differences. System produces following posting
40/50 advance
50/40 exchange differences (CI 30)
and doesn't allow the posting with the errors FI057  -  no invoice key or no VOBELNR.
I tried to put on advance account commitment item of all types (60, 90, 50) and none of them works.
The general question would be then how to handle business processes that include any kind of interim clearing when posting vendor and customer invoices.

Dear Tomislav
Please check whether this note is implemented in your system:
1012189 FMPU_R: Error message FI 057 for exchange rate differences
Should this is ok, then you should check whether your G/L account for  exchange rate diffs is correctly classified for document splitting, and your splitting method must be correctly linked to the transactions and item categories you are using (clearing operations, exchange rate differences...)
I hope this will be of help
Kind regards,
Mar
