Hi Varun,
Please try this procedure
1. Go to RSA1 > BI Content
2. Select InfoSource 0FI_GL_10 with the Data Flow Before grouping. If the transformation shows then install it.
3. If the transformation does not show then try selecting the 0FI_GL_10 DataSource with the Data Flow Afterwards grouping. If the transformation for InfoSource 0FI_GL_10 shows, then deselect every other thing but the transformation itself and install it.
4. If transformation is still not showing, delete the 0FI_GL_10 DataSource from BW and replicate it's metadata again on the application component and repeat the above procedure
Note that depending on your BW version there might be some RSA1 issues causing that infosource related flows are not shown after activating business content even though they are there, active. In that case I simply open another rsa1 mode and the flow shows.
Hope this solves your problem
Regards,
Fernando
