Regarding Columns Displayed option disabled in Product-Based Adjustment List Applet
Columns Displayed is unavailable on Product-Based Adjustment List Applet.
I have checked in standard application. In Product-Based Adjustment List Applet, the Columns Displayed menu item is disabled.
Navigation: Go to Administration-Pricing -> Discount Matrix and then drill down the Discount Matrix name.
In Siebel Tools:
Go to Applet : Product-Based Adjustment List Applet
Then go to Applet Method Menu Item : Columns Displayed (SWE)
Property :
Suppress Menu Item = TRUE
I have also set Suppress Menu Item = FALSE and then tested as per Configuring Siebel Business Applications > Configuring Menus, Toolbars, and Icons > Customizing Menus and Toolbars > Activating or Suppressing an Applet Menu Item. Columns Displayed menu item is not enabled.
