The catalog structure is probably predefined in a company and shall be the same in all generated product data files.
A recommended was to handle this is:
·In any MT project create a mtxml file containing the complete catalog structure, with all Catalog Sections but no Catalog Items. Also, the relevant translations shall be included in the file.
·Choose the File > Export Template menu command, the Export Template Wizard starts
·Page "Choose Template Type": select "Item Template"
·Page "Select Item to Export": check the file you want to use as template (in this case the mtxml file containing the catalog)
·Page "Select Item references": just click Next
·Page "Select Template Options": enter a meaningful name, and optionally a description and an icon
Now the new template is available along with the exiting item templates (Catalog, Hardware and ApplicationProgram).
Note: there is a problem with this Visual Studio template mechanism if the mtxml file contains an XML element with the same name as the file. Therefore, before exporting the file as template, we recommend to rename it as e.g. "X.mtxml".
