BP not replicating for multiple sales area data from SAP CRM to SAP ECC

Hi,

We are replicating BP from CRM to ECC, the BP is replicating for on sales area when we extend the same BP to other sales area it is not replicating.

SAP suggested to run a report daily for clearing the buffer. the BP is replicating perfectly after running the report but after few minutes the BP is not replicating.

New BP is replicating to ECC with single sales area. the Problem is when we try to extend the existing BP to other sales area.

With Regards
