ItemChanged on Matix

Hello,

I want to display a messageBox on documents marketing Lines only ig  ItemCode or ItemName was modified so i must test if the value was modified but the event  ItemChanged does not work (since 2004 !!!) .

I try to test my value with the LOST/GOT events but this event is triggered 13 times in SAP 9.1 PL10 if you have created RF on the rows of the matrix (or header)

Have you a work around ?

Kind regards

Bruno
