Description:
TIBCO Adapter for SAP does not support LINE DATA TYPE as Import/Export parameter type in a RFC enabled function module

Symptoms:
=========
Unexpected errors encountered while running the adapter or during initialization.
    
Impact:
======
Loss of Functionality.

Cause:
======
LINE Data Type is not supported by SAP RFCSDK libraries used by the adapter at runtime.

Workaround:
==========
If we are ready to make changes to the RFC ,please use any one of the below mentioned workarounds.

A)
1) Remove the parameters of LINE Data Type from Import tab
2) Define the same parameters under Tables tab.
3) Save the RFC and activate it.
4) Do a refresh schema in the Designer Project
5) Try running the adapter & BW process

B) Please point the RFC to the structure inside the LINE data type, instead of directly to the LINE data type.

If we do not want to do any changes in the RFC, we can use the following work around suggested by SAP Support.

Write a custom RFC function module wrapper that converts such (InterTable which appear in Import/Export Parameter) parameters to TABLES and EXTERNAL application calls this wrapper over RFC API. Here the advantage is, you do not need to change SAP standard BAPIs/RFCs.

Resolution:
=========
LINE Data Type is not supported by SAP RFCSDK libraries used by the adapter at runtime.Thus, the SAP Adapter can not support it. As per SAP Application support, they discourage users from using Internal Table type as Import/Export parameter type in a RFC enabled function module as it is slow comparing to using TABLES".

Thus, you would need to use one of the workarounds mentioned to resolve the issue.

Please note that the we have enhanced the TIBCO Adapter for SAP R/3 5.4.2 to provide more informative errors related to LINE DATA type while starting of the adapter.
