Changing the path of execution?

Question

HI,
I am implementing SCD in owb. Its working fine.
While impementing SCD for one dimension I used table functions.
While using dubugger, I mean while debugging, it is executing as we expected. But when I execute directly through deployment manager, its not working.
The operators and the flow of that mapping is as follows.
Source ---> sorter ---> Table Function ---> Joiner_1
Dim ----> Sorter ----> Table Function ----> Joiner_1
Now
Joiner_1 ---> Splitter ( The groups are 1) INS_NEW, UPDT_DUP)
(Here INS_NEW group is for inserting new recors, which are not available in dimension )
( And UPDT_DUP is for the records, where the depending attributes are changed. So we need to expire the old records, and need to insert the latest records,)
Splitter Group - INS_NEW ---> Table Function ---> Target_Table (Insert mode).
Splitter Group - UPDT_DUP ----> Target_table (Update mode for expire the record)
Target_table (Insert mode for insert latest records)
Here the problem is this is working fine while debugging the mapping. But while executing the mapping its not working as we expected.
Later I found that, there is problem at the Joiner_1 point.
So then, I divided the above mapping into 2 mappings. and the flow is as follows.
Map 1
Source ---> sorter ---> Table Function ---> Joiner_1
Dim ----> Sorter ----> Table Function ----> Joiner_1
Now
Joiner_1 ---> Temp_Result_Table
Map 2
Temp_Result_Table ---> Splitter ( The groups are 1) INS_NEW, UPDT_DUP)
(Here INS_NEW group is for inserting new recors, which are not available in dimension )
( And UPDT_DUP is for the records, where the depending attributes are changed. So we need to expire the old records, and need to insert the latest records,)
Splitter Group - INS_NEW ---> Table Function ---> Target_Table (Insert mode).
Splitter Group - UPDT_DUP ----> Target_table (Update mode for expire the record)
Target_table (Insert mode for insert latest records)
Now, it is executing fine.
The reason why it doesnot work in the previous case is (according to the generated code),
Source ---> sorter ---> Table Function --->
Dim ----> Sorter ----> Table Function ---->
Joiner_1 --->Splitter ( The groups are 1) INS_NEW, UPDT_DUP) ---> Target Dim Table
Source ---> sorter ---> Table Function --->
Dim ----> Sorter ----> Table Function ---->
Joiner_1--->Splitter ( The groups are 1) INS_NEW, UPDT_DUP) ---> Target Dim Table
So by this, here, it is not preserving the joiner result. It is again performing the join operation.
So the results are not coming as we expected.
Here I would like to know, can we set any option like break point, such that, the OWB can perform that join operation once for that mapping at break point?
Any suggestions are welcome.
Thank you,

Just go through the documentation of ClassLoader, I hope you would definitely get some solution for this. Hope this helps you.
