Not able to replicate PO's and confirmation from SRM to ECC

Hi team,

We are not able to replicate po's and confirmations form SRM to ECC.

This issue is pertaining from yesterday

All the connections are fine ,Can somebody help us.

We are in SRM 7.0

Po's are getting created in SRM and not getting replicated in ECC system we are using extended classic scenario.

The same with confirmations,Confirmations are getting created in SRM and IDOCs are not generated which transfers data from srm to ECC.

Thanks,

Sai
