iDOC Status 51

Hello SAP Gurus,

I received an iDoc status 51. I tried reposting the iDoc in the logical system using BD87.

However, I still received the message: Logical system for CTR XX00/P8867920 inconsistent

I had maintained and checked the Master Data for this cost center and I have consistent logical system.

What could be other causes of the error? How can i reverse the iDoc posting?

Thanks,

Harvey
