PI System not displayed in EWA summary

Hi all,

we face the problem that one of our customers systems is missing from the EWA summary but the report is generated and sent every week to the customer.

Our solution manager is 7.1 with SP12,

ST-A/PI    01R_700    0001

ST-SER    701_2010_1    0025

ST-PI    2008_1_700    0011

SAP_BASIS    702    0015

Any ideas where to look for the error or problem ?

Thank you in advance for your answers.
