Hi,
Landscape is not an issue.
Can you check ECC Dev and BW quality have proper logical mapping configurations.
Please ask your basis team to recheck those settings.
Along with the table which is shared by harish, you can check table - RSBASIDOC. You need to check mentioned tables at bw quality.
its table need to have bw quality and ecc dev technical names.
From RSA1 Also you can check source system assignment details
RSA1,, menu Tools --->
conversion of logical system names
Assignmnt srce system to source system id
Which version of your using 3.x or 7.x?
if your on 7.x Then why your collected info source into transport?
if your ecc dev and bwq connections are in place then
1. First replicate ecc dev data source to Bw Quality.
2. collect bw dev active data source into transport and move to bwq.
3. Later move cube,transformations,info pack and dtp. for each object collect into new transport and move them one by one.
Thanks
