Creating UDF Under Tax Invoice

Hello All,

I've created a UDF under Tax Invoice-Lines in the user-defined management screen, but the UDF is not displayed in the Invoice Documents. Please suggest, where can I get this particular UDF (Marketing Documents).

One more question, I've created a UDF under row in marketing documents, but the problem is it displaying in the documents , but it's not active that is, I am not able to add any data. Even, I've reviewed the settings under 'Form Settings' also, the field active is grayed out.

Please suggest suitable solutions for the above 2 issues.
