Follow on documents not getting updated in SRM.

Hi Experts,

Can any one suggest me a solution, As the follown on document status is not getting updated in the SRM,

I checked in BBP_PD and where i can see the PO number in Core key, But it is not getting updated in header links as Obj_key, BUt i can see the PO in the backend R/3.

I the queue is increasing in the application monitoring.

The BBP_GET_STATUS_2 is also exceuted and did not find any improvement. could be also a performance issue with this job.

Please suggest me some solution for this.

Regards,

Sairam.
