Can anybody help me with this query. since i am a beginner in abap.

this is my requirement

i have to do a recording using shdb(i have done that for xk01 t-code. i have given entries only for the mandatory fields).

then based on that i have to write a code to export data from a flat file on my desktop(presentation server).

i have done till this.

the next requirement is that i have to use alv block display to show a block to display the vendor name and all the records which were populated and success message if records are populated from flat file into the system.

else if i have errors then i have to show another bock containing the error messages. can anybody help me with that?
