tRFC Failure - Work Flow getting delayed

Hello Gurus,

I need your urgent help regarding the following matter:

System: SAP SRM

Release: EHP3 for SRM 7.0

NW: 740

There is a tRFC failure in our system.

The maximum runtime for a worl process is: 3600 seconds.

This leads to a lock on table PPFTTRIGG.

As a result of which all the workflows are stuck and there is a serious impact over the business.

We have identified the problem in lines with SAP Note: 1388980.

But unfortunately the note is not relevant for our release.

Need some urgent help to resolve this tRFC error.

Thanks

Rishabh Goel
