AR invoice receivable accounting for retaintion money

Hi All,

I want to track retention money in separate receivable account. How do I split receivable account on AR Invoice. ?

e.g. we have manual invoice to create for $100 where $90 should go in 10001 receivable account and $10 should go in 10002 Receivable account..

I created invoice manually, Insert one more line in the AR Lines  with negative amount of retention and change the distribution to the

Retention Receivable account.I want to insert the  Retention Receivable account automatically.

Could you help me to solving this problem ?

Regards,
