The compilers search for dependent files such as COBOL copybooks in the folders defined on the Copybooks tab of the Build Path page in the project’s properties (click Micro Focus > Build Path in the project’s properties). This tab enables you to include specific folders and also to control the search order.

If you have imported copybooks using a virtual folder in your project, you need to add them to the project's dependencies - navigate to Micro Focus > Build Path in the project's properties. On the Copybooks tab, check the copybook paths that correspond to the folders that include the imported copybooks, and then click OK.
