Performance of bapi BAPI_SALESORDER_CHANGE.

Question

Now we meet the reqeust to split the order item by quantity in order to assign wbs number to each material
For example the sales order contains one item with 10 Qty and we need to split to 10 items and each item with 1Qty
Order:
     Line 0001          Material            10Qty
Change to:
    Line  0001          Material            1Qty      WBS-001
    Line  0002          Material            1Qty      WBS-002
    Line  0003          Material            1Qty      WBS-003
    Line  0010          Material            1Qty      WBS-010
We used bapi BAPI_SALESORDER_CHANGE to do above process but the run time seems very slowly (time out)
I tried to delete the schedule_lines and schedule_linessx from import for test.
it runs fast but the result is there is no quantity in each line item.
without schedule_line import, the order will be:
    Line  0001          Material            0Qty      WBS-001
    Line  0002          Material            0Qty      WBS-002
    Line  0003          Material            0Qty      WBS-003
    Line  0010          Material            0Qty      WBS-010
Does any one tried BAPI BAPI_SALESORDER_CHANGE and met the same problem (slowly)?
And any suggestion?
Thank you very much!

Hi,
BAPI_SALESORDER_CHANGE should not raise time out,
unless you process huge amount of data.
Maybe some data are locked or some user-exit causes infinite loop or incorrect select on large table.
Try to perform runtime analysis with small amount of data,
and during execution check SM12 for locks and SM50 for sequential reads.
