matching open items doubt
in FB05 first screen, at the first line item, i entered PK 50 and open item managed account A.
on second screen, i provide amount 600 and hit enter and provide another open item managed account B.
1) why $600 at amount entered field is 600- and i need to find PK 50 in assigned field only can return 0 in not assigned field.
2) the list to match is for account B and PK for account B is 40 so why amount entered is referred to credit 600 and not debit 600?
3) the double entry shows is CR account A and DR account B but why in matching screen which list account B account items i need to look for PK 50. confusing me.
