Hi Prasad,
I had the same problem. In APD, in the field assignment ("transformation"), I've clicked on "Display Data" and I get the error message bellow.
Move variable from Default Values to Characteristics Restrictions
Message no. RSCRM261
In my query I had a filter in "Default Values" (right side). It seems that APD only accepts filters in "Characteristic Restriction" (left side). After changing my query my APD worked fine.
BR,
Marco Modesto.
