CL_GUI_ALV_GRID --> Syntax check with uploaded data
I have a internal table that I display with the class CL_GUI_ALV_GRID.
This list is editable. After editing the user can do a syntax check. All new entered rows or
Modified cell values will be checked using the object ER_DATA_CHANGED of method handle_data_changed. I check some logic and if there is something wrong I add an entry to the protocol by call method er_data_changed->add_protocol_entry etc.
Now I want to add a new feature to my list.
The user should be able to upload a .csv file from his presentation server.
Well The upload works fine. I get all the uploaded data in my ALV. But and this is my problem: I am not able any more to make a syntax check, because none of the uploaded data is in the object ER_DATA_CHANGED.
Do you have any idea how to solve this? I searched for a method to add inserted rows manually .
