Posting FIDCCP02 IDoc in R/3 via XI

Hi,

I am trying post FIDCCP02 IDoc in R/3 via XI.

My IDoc reached R/3 but it is with status 51.

Status text: IDoc: 0000000000951048 Status: Application document not posted

T100 Text: Accounting transaction not permitted for posting in FI/CO

Please throw light on this.

Thanks in advance,

Manikandan Rajendran
