BOP is not updating some sales orders and keeping the status as Sent

Hi Experts,

When I run BOP in batch mode I am able to get update for most of the sales orders. For few orders I am getting the status as sent. I am able to see the status in BOP_RESULT update status.

When I see the credit block in Schedule line type/Event_Type is having 2 entries. But still the orders are not getting updated in ECC side.

I am running BOP in update mode only.

Please find below screen shots for Un confirmation BOP results in background:

BOP run in foreground:

Credit check in table: /SAPAPO/SCHEDLIN:

Sometimes I am getting Run time errors after BOP in ECC.

But not able to get why the errors are getting created.

Please suggest why the orders are not able to get update in ECC.

Thanks & regards,

Bala.
