Parameter and Type

Opt.

Description

node_table
 TYPE TREEMLUNOT

  

An internal table in which each line represents one node whose attributes you want to change. You specify the key of the node, and enter a new value for each attribute that you want to change. Each changeable attribute also has a corresponding flag with the name U_<attribute> . You must check this flag for each attribute that you change.

For example, if you want to change the hidden attribute for a node from ' ' (not hidden) to 'X' (hidden), you would enter 'X' in the HIDDEN field and 'X' in the field U_HIDDEN (to indicate that the field must be updated). If you want to change all of the changeable attributes for a given node, you should check the U_ALL field instead of all of the individual U_<attribute> flag fields.

The line type of data type TREEMLUNOT is made up as follows:

  • It includes the structure TREEMLNODT. In these fields, you can enter the changed values.
  • For each changeable value, there is a flag field u_<attribute> , which must have the value 'X' for each attribute you change.
