Hi Yann,
You should have QRTARW90.QRW, QRTARB90.QRW and QRTARZ90.QRW tables installed. If not, then your Adagio Receivables 90A upgrade has not installed correctly. Should the standard reports print correctly when using Receivables 90A, such as batch listings or customer lists, then the tables are there and the problem lies in the workstation setup, which you should re-do.
If Adagio.ssi doesn't list All tables, then you have a different install problem. You probably should run the CHKSYS.EXE utility to ensure that all the report tables are visible from your workstation.
There is a particular process for converting up reports from the 81A table to the 90A table, involving Aliases. We have this documented on our partner area of the website, so if you don't have access then you can ask your Adagio consultant for this document.
