Customization in Service Call Materials

Mario Byttebier

Hi,
when i add the materials needed, i would like to preset the warehouse in which the materials are stocked.
Therefore i need to make a formatted search or an optimalisation rule with customize.
The form is called SWA_CT_EffortMaterial
The item is called G_M_Mat
The column is called ItemCode
When i try using this code, i dont get the value of my itemcode ?
Matrix m = Matrix.GetFromUID(pVal.Form, "G_M_Mat");

string ItemCode = m.GetValue("ItemCode", pVal.Row-1);
SwissAddonFramework.UI.Dialogs.MessageBox.Show("Item = " + ItemCode , "INFO");
What do i do wrong ?
thx,
Mario
