Solution: using the SysInfoAction_TableField class

Using the SysInfoAction_TableField class, you can easily add this functionality in your displayed messages. The job beneath shows first a normal information message. The second information message however can be double clicked by the end-user. Double cliking it will open the Customer form on the Customer determined in the X++ code. (in stead of double clicking, the end-user could aswell click the Show button in the Infolog).

static void customizeInfolog(Args _args)
{
    CustTable           custTable;
    ;
    
    select firstOnly custTable
    where custTable.AccountNum  == "1301";
    
    info(strFmt("Normal info message about customer %1"
                ,custTable.Name));
    info(strFmt("Information message opening the CustTable "
                + "Form on customer %1 upon double clicking "
                + "the information message"
                 ,custTable.Name)
         ,""
         ,SysInfoAction_TableField::newBuffer(custTable));
}
