Is there a tool with the acronym SSDR, which could be described as follows:
Used as a hub for the exchange of data between systems SAP ECC and BW as a main reportinga system.

Found in the help SAP the following references:

"for subapplication remuneraƧƵes para Determinar o DRI (SSDR)"

"for the routine determination of the salary for DRI(SSDR)"

Not like "hub for data exchange". From SAP to exchange data PI\PO used.

And here's another:
Supplier Service Defect Rate (SAP)
The ratio of the defect provider

It's amazing how much you can shake out of 4 letters.
