Status not tranfer to dependent objects

Hi Guys

There is seems to be issue with SAP std, Actually I have deactivated the functional location status (INAC). Therefore the same effect should come into its dependent equipment (installed) as deactivated (INAC). Even the SAP pop up information (Message no : IL420) is also reflecting the same, however it is not succeeded in real system.

Can you tell me what is the reason ? How to solve this issue?

Regards
