FBU8 Reverse Cross Company Issue

Hello,

I have a unique situation that I can't figure out.  One of our A/R clerks posted two cross company code transactions.  The situation is this.

InterCo #######1

Co 8500 Doc #####899

Co 8520 Doc #####402

InterCo #######2

Co 8500 Doc #####891

Co 8520 Doc #####400

She reversed all subsequent postings so she could reverse these two intercompany documents.

Reversed Intercompany ######1 with message #####899 reversed but ######402 not reversed.

Reversed Intercompany ######2 with message #####891 reversed but ######400 not reversed.

Now, #######400 will not reverse because it has a cleared document that was cleared by ########402

#######402 will not reverse with the error that document has cleared items but there are no cleared items other then the cross company doc with should be cleared with the cross company reversal.

Please help.

Thanks

Rick
