Open Item analysis of AUC GL account

Dear Experts,

In my company, we have asset class for AUC. We capitalise through AUC, that is first everything is debited to AUC then from there it is capitlise to fixed assset. My question is, when I capitalise from AUC to fixed asset that capitalised amount gets cleared from AUC asset, but from Geneal Ledger of AUC it does not get cleared, Due to this, it is very difficult to analyse the open item from General Ledger Account line item.What is the way to do this?

My first thought is, I would substitute Fixed Asset Number in both the line items of capitlisation entry so that user can sort on assignment and know the exact open items in general ledger. But in asset substituion as wel I could not find these fields/tables.

Need your help to resolve this issue.

Regards
