SAP SAP BC compkgsapBCException null

Hello,

Hi,

I have a problem regarding communication between SAP R/3 and SAP BC.
In SAP’s log RFC transactions (SM58), it’s shown the following error:

FM: IDOC_INBOUND_ASYNCHRONOUS
Error: com.pkg.sap.BCException : null

I don`t have more information. Two questions:

  1. Where can i find more info to analize this error ?
  2. Have you ever seen this error before ?

I can not replicate it, because it occurs randomly.

thanks,

Ralph
