I was trying to make an inventory transfer from adpaters so i can make the transfer but only using the same lotnum , i need to make the transfer from a lotnum to a new lotnum but the system requier “A lotnum valid is required”. I try to use the the ChangeLot() method but i dont know how it is working  
any help`?

My code

string PartNum = “275552TIWANDERSPO+” ;string UOM=“KILO”;  
InvTransferAdapter invTransferAdapter = new InvTransferAdapter(oTrans);  
invTransferAdapter.BOConnect();  
InvTransferDataSet transferRecord = invTransferAdapter.GetTransferRecord(PartNum,UOM);  
invTransferAdapter.InvTransferData.Clear();  
invTransferAdapter.InvTransferData.Merge(transferRecord);  
invTransferAdapter.InvTransferData.AcceptChanges();  
InvTransferDataSet.InvTransDataTable table = (InvTransferDataSet.InvTransDataTable)invTransferAdapter.InvTransferData.InvTrans;

```
					if (table.Count != 0)
        				{
						
				DataRow dr = table.Rows[0];
            			dr.BeginEdit();
            			dr["TransferQty"] = 2;
            			dr["FromWarehouseCode"] = "03";
            			dr["FromBinNum"] = "A1";
            			dr["FromLotNumber"] = "178490377001621";// my lotnum
            			dr["ToWarehouseCode"] = "04";
           				dr["ToBinNum"] = "A1";
            			dr["ToLotNumber"] = "178490377001621CC"; // New lotnum
            			dr["TranReference"] = "mov ext fiscal";
            			dr.EndEdit();
						
						
				string str6;
            			string str7;
            			InvTransferDataSet.InvTransRow row1 = (InvTransferDataSet.InvTransRow)table.Rows[0];
            			string partNum = row1.PartNum;
            			string fromWarehouseCode = row1.FromWarehouseCode;
            			string fromBinNum = row1.FromBinNum;

            			decimal pdTranQty = 1M;

Enrique,

Does this script work if the lot does not change?

Hi duckor  
Yes it works if a use the same lotnum (E.g 178490377001621 to lotnum 178490377001621)  
but if i try to use a new lotnum the system says “A valid lotnum” is required.

Thanks & regards.

So when running it manually I notice that a lot change prompts to create a new lot. This is the step you are missing which I believe is from LotSelectUpdate. When the lot for that part existed already it does not prompt. So the first time I used my script to transfer from lot 123 to 321 it wouldn’t work. When I manually did it my script then started working since it now existed and ChangeLot was not required.

I’m 95% sure LotSelectUpdate is what you need to be looking at but I haven’t dug into how to use it.
