GetItemExtention failed - how to go about resolving?

Thank you, Leo.

I figured it out - when creating a field on a table I had mistakenly typed LiveRevision instead of LineRevision resulting in two fields being added to the table.  No big deal.

When the upgrade came around to my desk I looked at the definitions and thought that maybe the upgrade had duplicated the field definitions. I didn’t see the difference between ‘v’ and ‘n’ and deleted the LineRevision field.

The field is still in the DAC so the project compiles. 

So when trying to reference POReceiptLineExt.UsrLineRevision - it didn’t exist in the database table causing the error.

With regards to your thought/concern:

> You might need to loop through all detail lines to copy the values.

Fortunately, the Copy method is called for every line. I think it was designed exactly for the purpose of making it easier for customizations to copy values from POLine to POReceiptLine. It only works if the fields are actually available to copy to, however. :)

As it turns out Leo, I did also have to write my code as you suggested.

POLineExt srcDAC = Base.Caches[typeof(POLine)].GetExtension<POLineExt>(aSrc);

POReceiptLineExt destDAC = Base.Caches[typeof(POReceiptLine)].GetExtension<POReceiptLineExt>(aDest);


destDAC.UsrLineRevision = srcDAC.UsrLineRevision;
