User Authorization don't work in MD01.

Hi!

I created the role with  transaction MD01 only.

System generated two Authorization Objects:

1. S_TCODE - Transaction Code Check at Transaction Start:

MD01

2. M_MTDI_ORG - Organizational Levels for Material Requirements Planning:

MRP Controller (Materials Plan...

Activity types in materials pl MRP: total planning

Plant                          Unmaint. org. level

Next, I can don't write values of "Plant" or "MRP controller"  in  Authorization Objects M_MTDI_ORG. I can even delete Authorization Objects M_MTDI_ORG!

But the user with this role(only this) still can not only open MD01, but successfully complete planning. For any Plant or MRP controller.

Why it don't work? What i can do? I need to limit user authorization and i don't want to create Z-transaction for it

Thank you

Best regards,

Evgeniy
