Paramters empty when using Transaction launcher wizard for BOR Method

We have a u201CCRM 5.0 BOR method based - action boxu201D; that uses a R3 method, to pick the confirmed BP from CRM CIC and goes to R3 and finds a partner function for it. We are moving over to the navigation bar in CRM 7.0. We are using the transaction launcher wizard in CRM 7.0 to create a launch transaction for this action box. In the wizard we enter the following: 1) Name, Component set: u201CALLu201D; 2) Description and Custom Class name; 3) choose A BOR Transaction, choose the R/3 system we are connecting to and choose the appropriate BOR Object Type and Method Name. The problem is when we go to the next screen u2013 u201CTransaction Parametersu201D u2013 nothing shows up in the dropdown box.

From what weu2019ve read, we need to choose something here. Eventually we will have to go to the method u201Cif_crm_ic_action_handler~PREPARE_DATA_FLOWu201D in the class specified in the wizard and change to code to use the confirmed BP number. But first we need to choose the transaction parameter in the wizard. I think maybe we need to choose a component set on the Entries screen but there are a bunch of them and we have no idea which one is appropriate. It could also be a declaration in the method!!

We have checked the settings for the ZTSTC object, the ITS URLs, the RFCs and logical systems and came up with noting. These are the notes that we have checked: 1021222, 888931, 1337200 and 1337472.

Does anyone have an idea as to what we might be missing?
