Queries on ALV Reporting

Hi,

This is sandeep..

I have few queries on ALV Reporting…

Mainly while executing the ALV report I am getting error in source code as <u>Read report l_prog_tab_local into l_abap_source</u>… What meant that????

I am getting exception like this…what meant that exception???

<u>Runtime Errors: READ_REPORT_LINE_TOO_LONG

Exception: CX_SY_READ_SRC_LINE_TOO_LONG</u>

Another query is what are the <u>SET PARAMETER and GET PARAMETER</u> in USER_COMMAND of REUSE_ALV_GRID_DISPLAY function module in ALV Reporting…. What is main difference between SET PARAMETER and GET PARAMETER???

Please help me on my queries...i am looking forward your's help on those issues...!
