SAP Instance profile parameter inconsitency

Hi All,

Once we performed upgrade from ECC EHP5 to ECC EHP7 , whenever making any changes to instance profile parameter from SAP level and doing a system restart , it is removing start profile parameters values from instance profile. Due to this system was not comming up.

Did any one face this issue. Is there any solution for this inconsistency.

Kindly suggest me.

Thanks

Pradeep.
