You are getting that error because ExecuteNonQuery() returns an int not a DataTable.

Well your first issue is that ExecuteNonQuery returns an integer value and not a datatable.
SqlCommand.ExecuteNonQuery[^]

My next question is, what does your stored procedure return? Is it a table?
Why did you change from using the DataAdapter.Fill approach you started with?

If your stored procedure returns values, then you will want to look at using the following:

SqlCommand.ExecuteReader[^]

As the previous poster mentioned, It looks like you forgot your SqlDataReader.

Try something like this:

C#

DataTable dt = new DataTable();
conn = new SqlConnection(ConfigurationManager.ConnectionStrings["LOUPe_InventoryConnectionString"].ConnectionString);
conn.Open();
SqlCommand cmd = new SqlCommand("procWebLossRatioAnalysis_G_RP_LR", conn);
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.AddWithValue("@pSNLCompanyName", snlcompanyname);
cmd.Parameters.AddWithValue("@pReportTypeFlag", reporttypeflag);
cmd.Parameters.AddWithValue("@pSNLStateLOB", snlstatelob);
cmd.Parameters.AddWithValue("@pForYears", foryears);
cmd.Parameters.AddWithValue("@pPerformance", forperformance);
cmd.Parameters.AddWithValue("@pLOBGrpList", lobgrouplist);
cmd.Prepare();
SqlDataReader dr = cmd.ExecuteReader(CommandBehaviour.CloseConnection);
dt.Load(dr);
grvMergeHeader.DataSource = dt;
grvMergeHeader.DataBind();

I would request you to refer this link as it gives you the information about the ASP.Net Data Providers
with sample source code.

Hope this would give you more sense on ASP.Net Data Providers.
