InfoSource 0FI_GL_10 (Transaction Data) is not known

Gurus,

If I try delete 1. Transfer Structure or 2. DataSource, I get the error shown 3. "InfoSource 0FI_GL_10 (Transaction Data) is not known"

How can I delete this datasource and all dependent objects? Is there a force delete abap program?

All of this is happening in a brand new BW 7.3 Test system started from a system copy of the current 7.0 BW test system.

I've also tried 3 tables:

-  RSDS (DataSources) -> No entry found 

-  RSIS (InfoSource)  -> 1 entry found (I've requested delete access from security team)

-  RSTS (TransferStructure) -> No entry found

Appreciate any help with deleting this datasource and all dependent objects.

Thanks,
Gregg
