The subdocument support will always continue if it failed to include one or more subdocuments.
The pre-include phase for subdocument takes place during Model creation, before the actual translation of the model document. ITP generates an error document if subdocuments could not be found during the include phase. This error document contains all successfully included subdocuments and error messages for the subdocuments that ITP could not find.
If you added the setting
ITPALLOWMISSINGINC=Y
to the configuration file, ITP will remove the __INC statement and continue model translation without generating an error if the subdocument can not be included.
The post-include phase for subdocuments takes place during Model execution, after the actual execution of the model. If ITP could not find subdocuments the user will be presented with a PST0005 error message and no output will be produced. It is possible to obtain an error document (such as produced in the pre-include phase) by adding the setting ITPRECOVERPOSTINC=Y to the configuration file (Using this setting in a production environment is discouraged).
If you added the setting
ITPALLOWMISSINGPOSTINC=Y
to the configuration file, ITP will remove the __INC statement and continue model execution without generating an error if the subdocument can not be included.
