Field help (AVWCODACT) 

The Activity Code and the Module that are used to identify if the view described in the dictionary must be created in the database of the folder. It is if the two conditions set out below are achieved simultaneously :

 the activity code field is empty or that the activity code (defined in the corresponding view) is actually activated.

 the module to which the view is attached has been declared active for the folder.

A view with an assigned activity code starting with X, Y, or Z, is considered to be specific/custom and in no case affected by a version change (these activity codes can be placed at the line level).
