BW Measures not being updated in PAS

Dear All,

I am facing this issue many times. Whenever i am updating my BW Query in PAS, sometimes the PAS is updated and sometimes the date shows it is updated but actually it does not update PAS. Even sometimes i have noticed that, out of 10, there may be 1 KPI which is not being updated and rest 9 being updated.

Before updating "Import Schema" or "Import Data" , i always kill the session from PAS and also restart JPIP.

How i solve this, i keep trying and after 5 6 tries it loads or change the KPI Measures spellings in BW Query

Anyone having similar issues and what possibility could be there for not updating PAS. We are using SSM10, SP7 HF1.

Thanks

Mo
