Parallel processing during BP replication

Hi All,

We are replicating BPs from ECC to CRM using requests (R3AR2). We've divided the entrie load into 20 parts as follows :-

REQ1 - 10,000 BPs

REQ2 - 10,000 BPs and so .... till REQ20

When we start these requests from R3AR4, we noticed only one request is running at a time; meaning when REQ1 is completed then REQ2 is started, when REQ2 is completed REQ3 starts and so on.

We want all of these requests to run in parallel since we've 40+ Dialog work processes in ECC and CRM.

Any idea why are the requests not running in parallel ?

Note - We've already set the parameters as follows :-

MAX_PARALLEL_PROCESSES = 20

CRM_MAX_NO_QUEUES_PER_REQUEST = 10

Thanks,

Ashish
