How to show few messages for each row in ALV

Hello,

I have an ALV with multi-select of rows. I also have few buttons which process all selected rows (bapi's and so on).

For each bapi that failed, I want to show to the user all error messages that the bapi return. The user should know the row in the ALV that each error message refer to.

I can't use the report_attribute_message method because the messages disappear if I scroll down the ALV or do other simple actions. In this way the user will miss the many messages.

Do you have an idea?

Thanks,

Ednri.
