Asset SLA - Account rule logic - change category

Summary

How to create an Account Rule which targets a specific Asset Category (when moving to and from it)

Hi All,

I need to create an (Asset SLA) Account Rule which produces a given code segment value in specific conditions - in this case when changing the asset category to and from a particular one (lets call it Category A).

So... When changing asset No.12345 from Category F to Category A I want the SLA process to select a code value of 1234 - I thought that use an Account rule with a Constant Value Type and Value 1234 would work if I used the condition below, however... whilst it produces the correct code for the destination cost and depr reserve it doesn't produce the correct code for the source cost and source depr reserve.
