Length problem on a grid.

Question

Hello,
I have a problem with grids in my add-on.
I have to generate 2 grids where the datas are exactly the same (so the associated XML definitions are the same too) but come from 2 different user-defined tables (1 grid for each table).
On both of these tables, the datas that I have to display in my grids have the same type and size, but in one of my 2 grids the fields max length is not correct (multiply by 2) whereas the other is fine.
I populate these 2 grids exactly the same way, by generating a query with the function ExecuteQuery.
After several tests, i can say that the problem is not in my XML file or in one of my Grid object. It seems to come from B1 not retrieving or modifying the size of the fields in one of my table.
Can somebody help me, please ?
Thanks.

Hi Helen,
here is my code.
     'Declarations and initialisations
    Private muc_grOperationsSO As SAPbouiCOM.Grid
    Private muc_grOperationsTL As SAPbouiCOM.Grid
     muc_grOperationsSO = CType(FormItem("grOPSO").Specific, SAPbouiCOM.Grid)
    muc_grOperationsTL = CType(FormItem("grOPTL").Specific, SAPbouiCOM.Grid)
    muc_grOperationsSO.DataTable.Clear()
    muc_grOperationsTL.DataTable.Clear()
     'Grid generation
     Dim dst_CodeSQL As String = ""
     ' Request SO
    dst_CodeSQL = "SELECT TOP 2 OP.Code"
    dst_CodeSQL &= ", OP.U_CodeOP"
    dst_CodeSQL &= " FROM [@MRO_SEO2] OP "
    dst_CodeSQL &= " ORDER BY OP.Code"
    muc_grOperationsSO.DataTable.ExecuteQuery(dst_CodeSQL)
     'Request TL
     dst_CodeSQL = "SELECT TOP 1 OP.Code"
     dst_CodeSQL &= ", OP.U_CodeOP"
     dst_CodeSQL &= " FROM [@MRO_TAL2] OP "
     dst_CodeSQL &= " ORDER BY OP.U_CodeOP"
     muc_grOperationsTL.DataTable.ExecuteQuery(dst_CodeSQL)
In this case, I have 2 grids and both display 2 columns : "Code" and "U_CodeOP". "Code" is defined on 8 characters and "U_CodeOP" on 4 characters on my 2 table MRO_SEO2 and MRO_TAL2.
In my grid TL, "Code" is displayed on 8 characters and "U_CodeOP" on 4 characters (Normal behavior)
In my grid SO, "Code" is displayed on 8 characters and "U_CodeOP" on 8 characters instead of 4.
I don't understand why B1 doesn't retrieve the max length for this field in my grid because when I go to Tools > Customization tools > User defined fields management my "U_CodeOP" field is well defined (on 4 characters).
Let me know if you want to see the XML code associated, I don't want to "flood" the post, but the XML code for both grids is exactly the same (copy/paste).
Thanks for your answer.
