BPE customizing not fully maintained

Hi All,

i am getting the below CCMS alert repeatedly,

CCMS ALERT for MTE: PX1 \ PX1_500_Business Process Engine \ Overall status \ Status of the automatic customizing

Alert Details:

System : PX1

Alert Text : BPE customizing not fully maintained

Alert Color : RED

Does some one give me any idea what could be the root cause of this message.

Thank You,

Madhav
