# Adding and linking components

## Procedure

1. Create a Job and drop the node *RFC\_READ\_TABLE* in the SAP Bapi folder of the SAP connection onto the design workspace as a tSAPBapi component to reuse the connection to the SAP system and the input and output schemas of the SAP function *RFC\_READ\_TABLE*.
2. Add the following components to the Job by typing theirs names in the design workspace or dropping them from the Palette:
   * two tFixedFlowInput components: to generate two input data flows for the *FIELDS* and *OPTIONS* input parameters of table type respectively.

     Note that there is no input data flow for the *DATA* input parameter of table type, since it does not need an input value in this example.

   * three tLogRow components: to display the output data corresponding to the *DATA*, *FIELDS*, and *OPTIONS* output parameters respectively.
3. Connect the first tFixedFlowInput to tSAPBapi using a Row > Main connection.
4. Connect the second tFixedFlowInput to tSAPBapi using a Row > Main connection.
5. Connect tSAPBapi to the first tLogRow using the Row > row\_DATA\_1 connection.
6. Connect tSAPBapi to the second tLogRow using the Row > row\_FIELDS\_1 connection.
7. Connect tSAPBapi to the third tLogRow using the Row > row\_OPTIONS\_1 connection.
8. Label the components to better identify their roles in the Job.
