Hi Rod,

How are you invoking this script?  Do you have it tied to a button the user has to press or do you have it connected to an event?

Thanks

Elliott

Panel - OnExit

This type of script probably better plays to a business object event.  You are probably receiving errors because it is trying to fire off your script when you leave the screen, which means the business object (which you are using) no longer exists and has been dropped.

You may want to put this script more on the "Pre-Write" event for the CI_Item_bus object, it all depends on whether you need this info displayed to the user prior to writing the record, etc.

Elliott,

When you view the screen result from "Compile" button, it lists it under a tree view as "Pre-Write", BUT, when I associate the script with the IM Inventory Maintenance using Customizer | UI Script Events the only "Panel - Post Load" and "Panel - On Exit" 

I would like the script to run whenever I change any data on the Item Maintenance Screen.

I suspect you need to delete the old script attached to the On Exit and then re-enter as per Elliott's suggestion.

Presumably you'd want your script to run if you imported items using Visual Integrator.  The PreWrite trigger will do that, but a UI script will not.

Delete the script file (in \MAS90\CM\Script\... named for the panel) and remove the panel UI trigger.  The PreWrite event happens for any modification to a record (plus new records).

No, No VI import involved.

User creates/enters an IM Item and is suppose to enter a "UDF_Pack" number which represents the number of "each's" in the Standard Unit of Measure (i.e. CS , BX, whatever) then the script calculates the UDF_Each_Cost.  The error at issue occurs when they don't enter a UDF_Pack number or when you "X" out of a blank IM Item Maintenance screen.

It would optimally trigger after the UDF_Pack number is entered, but the only place I could see to place a script in the screen panel customization was with a Panel-Post Load or Panel-On Exit.

I understand, but tying a script to the UI causes complications like you describe, so don't trigger it there.  Use a script on the CI_Item table (Pre-Write, or column post-validate) instead of the UI event.

I guess I don't know where to do this

pause...   I think I found it.

Many Thanks.  That worked.  The UDF calculates and there is no error.

To recap; I removed the script form the screen customization and added the script (using pre-write) to the CI_Item table.

Thanks again.
