Script to Update Item GL Class Assignments in OPM Inventory?

Question

We use OPM Inventory in our 11i.5.10CU2 process manufacturing environment. GL Class codes are assigned as categories to items in our OPM item master. We have a need to update the GL Class assignment to a new value for roughly 200,000 items. I've been researching API's to help with this, but unfortunately there are none available for OPM.
I logged a SR, and OPM development confirmed that there is no API to update OPM items, only to create brand new items. (When using the Create API you set the desired GL Class, but without an Update API there is no sanctioned way to then change it.)
I traced what happens when one saves a new GL Class category in the forms, and I can see it updating/inserting:
* ic_item_mst_b
* gmi_item_categories
* mtl_item_categories
Plus, some star schema tables (ENI?), but we don't use any BI products.
Does anyone have any scripts or experience with updating OPM item category assignments?
(Does this post belong in another forum? Not sure where it would be seen by the right audience.)
Thanks, Wolf Moritz

There are so many things that, in your environment, you might want to check to verify a server build that it is highly unlikely that anyone else does, or would want to do, the same tests.
You will probably have better luck asking separate questions about how to do some of the specific checks you want to run, and, possibly, how to use colour-coding to highlight in HTML.
I'll start you off by pointing out that what you make look complex can be done in a much simpler manner. For example, how you get the username from the username environment variable:
PS C:\Users\Al> $UserName = (Get-Item env:\username).Value
PS C:\Users\Al> $username | gm | select typename -first 1
TypeName
System.String
PS C:\Users\Al>
It is good that you are concerned with the type of value assigned, but there is a simpler way that works for all environment variables (all of which are strings):
PS C:\Users\Al> $UserName = $env:username
PS C:\Users\Al> $username | gm | select typename -first 1
TypeName
System.String
PS C:\Users\Al>
This also returns a string, but, in the process, the code is simpler and a bit more intuitive, at least in my opinion.
