Planning AutoSchedule does not generate Supplier Schedules in R12

We upgraded from 11.5.10.2 to 12.1.3. I ran our MRP process: Generate Forecast, Load/Copy/Merge MDS from the Forecast and Sales Orders, then Launch Planning Processes. I can see the demand in the MRP Workbench. I then submitted Planning AutoSchedule using the same paramters that we use when running it in 11i. The Supplier Schedule did not generate in R12. Here are the steps that I performed in order to verify demand:

(R) US MATERIAL PLANNER > MRP > Workbench > Select Organization = WD > Select Plan = WOODMRP > (B) Supply/Demand > Enter Search Criteria> Supplier Equals POROUS MEDIA CORPORATION > (B) Find > Data is in the SUPPLY DEMAND worksheet  (see attached document with data and screenshot of MRP Workbench in the 204667MRPWRKBNCH worksheet)
