Resolution:
Description
========
Created the global variable BW_GLOBAL_TRUSTED_CA_STORE and defined the Trusted Certificate Folder field to %%BW_GLOBAL_TRUSTED_CA_STORE%% in the SSL configuration in order to store the certificates outside of the BW project. When validating the project, the error is reported.

Environment
=========
ALL

Resolution
========
From the BW documentation TIBCO ActiveMatrix BusinessWorks Process Design Guide, Chapter 16, Working With Secure Sockets Layer (SSL), Trusted Certificates:

============================================================
4. Specify a value in the Trusted Certificates field in the SSL Configuration dialog. When the project runs, the value of BW_GLOBAL_CA_STORE overrides the value you specify with the location you provided.
============================================================

Create an empty trusted certificate folder in the project and refer to it in the SSL configuration-> Trusted Certificate Folder field. The value of BW_GLOBAL_CA_STORE will still be used during run time.

Error when validating a project: "The following reference is no longer valid: %%BW_GLOBAL_TRUSTED_CA_STORE%%."
