DS - Data Store - fetching tables from PRD

Dear All,

I have DS 4.1 Server running fine with all other source and targets.

I have a scenerio which is bugging me, Asking for work around or easy way.

DS - Data Store is importing tables fine when

1. SAP Ecc- Development  as Source and Oracle DB/BW as Target

Jobs are executin fine, but

DS - Data Store is importing tables are giving me error :

2. SAP Ecc - Production as Source and Oracle DB/ BW as Target.

Error: RFC CallReceive error < Function /BODS/RFC_ABAP_INSTALL_AND_RUN; RFC_ABAP_MESSAGE, (Changes to repository is not permitted)>

I kow that this production client has locked the changes to repository as its prod, please let me know how do i do a work around and import tables from prod or assist me with the best practice.

Thanks

Saleem
