Subject AW: [IBO] Problems with TwwIBOQuery and Params (Invalid Variant Operation - when opening detailquery)
Author Christian Kaas
I have to add, the value of the masterkey is 99990000000001!
If the keyfield contains less digits it seems to work!

Might there a problem in the inside of IBO with handling large integers
as artificial primary keys!?
Sorry i bought only a partial licence and cannot debug it by myself
(aarg!).
I embeded the workstation id into the IDs to be able to do replication
(first 4 digits obviously).
I can start the first 2 sites with ids 1 and 2 which will lead to
significantly smaller numbers but later on i need the full range...
