Hi,
1. Maintain the correct control cycle in ECC.
2. In EWM transaction /SCWM/PSASTAGE maintain the same information along with the PSA storage bin what you maintaining in Control cycle. Also if you dont know min/max quantities keep it blank. If you dont want to keep it material specific just maintain one entry with blank material number and PSA storage bin.
Thats all, it will work...
let me know if not working..
Thanks,
Sandip
