Form Personalized during addition and/quick addition

Hi...

We have a requirement to protect user entry of expensed asset. We will differentiate from asset key where only for asset key 'LVA' will get this personalization. Items need to be protects are:

1. asset cost, the cost of an asset should be >= 250001 and <= 1000000 (for manual additions/quick additions in Fixed

2. expense account should be taken from expense account in AP Invoice (if we put track as asset yes in ap Invoice distribution lines during invoice entry)

Please advice
