The MELCU manual allows airlines to create their own MEL following manufacturer specifications. The manufacturer for this manual is customer specific for operators.

The MELCU doctype functions the same way as the MEL doctype, however the MELCU has been created to allow third parties to create and load MEL records into a database via TraxDoc.

When uploading a document into TraxDoc, the file that is being uploaded must be in a location where the eMRO server will recognize it. See below instructions:

- The IT department on the user side must select a directory to work as a repository for all the OEM manuals that would be uploaded to eMRO via the TraxDoc module.
- This directory must be accessible from the application server (Wildfly).
- Create a way for users to provide the OEM manual revisions to be placed in the repository.
- The path for the repository directory will be defined by the traxdoc_manual variable on the data.source.properties file. This can be found under the application server (/%WILDFLYHOME%/deployments/emro.war/WEB-INF/classes/resources/).

SaaS customers should refer to the instructions outlined in this document in iCentral: SaaS - How to Upload TraxDoc Manuals.

Note: For the MEL and MELCU Doctypes, the Company selection in the TraxDoc Detail, General tab cannot be set to 'ALL', but must instead be set to a specific Company. The Company should be set to the same Company as the Aircraft that will be assigned to the TraxDoc through the Effectivity button.

Note: Effectivity can also be reviewed through the View MELCU Effectivity button.
