Sproxy: Can only see Basis Software Component

Hi Experts,

I am working on 7,4 dual stack PI.

Recently done with all the configurations in PI .But now I want proxy communication with ECC.

For this I created one H type and one G type RFC destinations in ECC to fetch ESR object from PI.

For now I have create only one SWC in SLD of PI and imported it in ESR .Created one Namespace under that.

But ,when I run SPROXY in ECC, it shows only SAP BASIS 7.4 software component and not the other SWC of ESR.

Do we need additional configuration for each of SWCV to get displayed in ECC SPROXY???

I refered the IDES system , in that too I noticed one thing that , out of all the SWC created in ESR of PI only few are diaplyed in IDES ECC SPROXY

why so?

Thanks in advance..
