Cannot add column to output of tMAP

[MarcusDidius]

Hello

I have inherited a Talend project from a colleague who quit.

I need to add an output column in a tMap. In my projects this is no problem.

However in my inherited project the add button is disabled.

I have no idea how to fix this... or what might be the cause.

It is the last column which I need to add to the tMap Output

Any help would be greatly appreciated.

HI @not specified not specified​ , maybe you can create generic metadata schema with all the columns + newcolumn then pass the output schema in repository and point to the schema instead of built-in in the tmap to force it.

Send me love and kudos
