Our AR Aging Report total does not equal the BalSheet AR amount (again).  While trying to determine why we discovered 2 new shocking issues:
 
1)  The BalSheet total for AR does not equal the Net transaction total for the AR on the  GL-C report!!  
 
And
 
2)  3 deposits made on the same day are not recorded in GL-C though they appear in the check register (are verifed by bank statement) and appear in AR-R payment history.   Fortunately(?) the total of the deposits equals the difference between GL-C net and BalSheet.  
 
But, What the heck!  -   Where does the BalSheet total come from?  How can transactions seem to have disappeared from the GL?
 
 
Does anyone know how this might happen?  
 
Meanwhile, we still need to deal with the original issue of why the AR Aging is different from BalSheet. The differences noted above are not the same amount.  I suspect the cause is related to payment reversals that didn't post correctly.
 
Any help greatly appreciated!
