BPM error (Rfc to file scenario)

Dear Experts,

I'm doing a RFC-FILE scenario with BPM. I have followed the blog RFC Scenario using BPM --Starter Kit by Arpit Seth.

The file is getting picked up. But in SXMB_MONI i get the following error:

<SAP:Category>XIAdapter</SAP:Category>

<SAP:Code area="BPE_ADAPTER">SYSTEM_FAILURE_INTERNAL</SAP:Code>

<SAP:P1 />

<SAP:P2 />

<SAP:P3 />

<SAP:P4 />

<SAP:AdditionalText />

<SAP:ApplicationFaultMessage namespace="" />

<SAP:Stack>An internal error has occurred</SAP:Stack>

<SAP:Retry>M</SAP:Retry>

In SXMB_MONI_BPE, there are no workflows for the integration process.

What could be wrong?

Please help.

Thanks,

Merrilly
