SAP System Performance lowered by sequential read access

Hi,

We have installed SAP Fiori Purchase Order application on top of ERP EHP6 on a embedded NW Gateway inside ERP

The report /IWBEP/CL_MGW_ABS_MODEL========CP triggers many SQL sentences to

REPOSRC table with sequential read which takes a long processing time. When we perform any task, the

system performance is worst because those reports.

We have followed the instructions given in notes/documents:

1889090 - SYB: Activating smartform is taking too much time - TRDIR

1749935 - SYB Configuration Guide for SAP ASE 15.7

DBA Cockpit: Automatic Table Maintenance for SAP Sybase Adaptative Server

The table's statistics are updated.

We have Sybase Ase 15.7.0.101 on NW 7.31/Windows Server.

How can we solve this issue?

Thanks in advance.
