IDOC Posting problem Through Billing Output Type

Dear Friends,

I have strange problem for IDOC posting through Billing Output Type.

We are using same output type for Partial / Final settlements through Billing Output type.

For Final settlements IDOC posted and generated account document is perfect, But for Partial settlement we are always getting message data is missing "No batch input data for screen SAPMF05A 0700 (Message no. 00 344)".

I tried to reprocess same IDOC in foreground then we are getting message "Posting is only possible with a zero balance; correct document"

(Message no. F5 060).

Could you please suggest me

Thanx in Advance.
