integration model itself invisible

Dear Experts,

I am into Rules based GATP , I want to transfer PLANTS,  ATP RECIPTS ,REUIREMENTS and STOCKS that is sitting in ECC to APO.

While transferring plants alone,through integ model  in CFM1 ,I get prompt IM model created,but in subsequent screens CFM2,CFM5 , the plant is not seen,(invisible)

Should I change model name ,logical system,APO application  or create a new one ,the model name,SAP04/logical system,APO SAP4 application is there already ,in the system created by someone .guess I need to contact BASIS for this rite??

Thanks
