Problem with 2LIS_13_VDITM datasource with 2 r/3 client

In the development system (SAP BI 7.0 SP 17) i have a connection to R3CLNT302.

My init didnt work because of a dump about mismatch about the logic systems.

R3CLNT100 <> R3CLNT302

So I decided to create a new connection for R3CLNT100, but it gave some errors (tables EDPP! and EDP13) in the activation.

then I deleted this connection but it deleted the parameters of the other connection 302.

A restablish these but now I can't activate the 302 client.

Created the 100 again and it activated and looked ok, but when I replicate the datasources, all but the 2LIS_13_VDITM appeared to me as 3.x. I want to use it as 3.x not 7.x. How can I get that datasource correctly??? Do I have to delete the other connection/client? I still have the old (from client 302) process chain, update rule and Infosource, should I delete it?

When I replicate the 100 client the only difference was with the 2LIS_13_VDITM, the rest of the datasources are 3.x.

Tahnk you all
