Issue with content in SPROXY

Hi Experts,

I have a proxy to IDOC scenario where we are using standard ESB provided by SAP. The ESB is installed in source ECC and XI content is installed in PI.

Now When we are using the standard content, we have a requirement to add extra fields. So I have created Data Type Enhancement. Now when I go back to ECC SPROXY for to activate the standarad proxy, The new Data Type Enhancement I have created in PI, are not showing. And whatever the changes I do in the SWCV are not reflecting in SPROXY.

Any Ideas?

Thanks in advance
