GRN Report

from where can i generate the reports for GRN details

You could try using the search [:D]

i go have go through the link but it showing the invoices detail, i want the GRN details like number date items etc

You did not go through the link it states:

Run the purchase line transaction where the line status is received. Only works as long as you do not part invoice full received lines. There is an accrued purchases report in the standard version from memory but it is not in the UK version and you need to ask your partner to add it.
