Dear Ankur
My FI consultant say's that the GL can't be changed as it's been created for Travel Advance & he's using the special GL Indicator "k" for Travel Advances. Now I'm confused totally confused here. I want the Advance amount to be deducted from the Expenses at the time of posting, but its showing the entire Expenses while posting which is making a mess. I've changed the Expert view settings with different combinations as 0,1,2,3.
when I'm using with 0 or 1 the Advances are not displaying in posting & its showing the entire Expenses which is totally incorrect in my case.
when I'm using with "2 or 3" I'm unable to post the Advance to FI while its showing the deductions in Posting like... Expenses - Advance.
Kindly let me know what else need to be done.
Cheers
