Assignment : How to get the data from Master table into entry form?

• Create the DIY fields such as UDF_PCS, UDF_CTN in Maintain Stock Item; and
• UDF_Price in Sales Documents (eg. sales invoice).
  
• Purpose is:

 Get UDF_PCS & UDF_CTN from Maintain Item to Sales Invoice Detail UDF_Price
 # If selected itemcode UOM is PCS then use UDF_PCS
 # if selected itemcode UOM is CTN then use UDF_CTN 
 # if selected itemcode UOM not PCS or CTN then default is 1 

• Calculation for Unit Price := UDF_Price * UDF_Rate

  end;
  Result := FComServer;
end;
 
procedure GetStockInfo;
var lSQL, lCode  : String;
begin

    lSQL  := Format('SELECT UDF_PCS, UDF_CTN FROM ST_ITEM WHERE Code=%s',[QuotedStr(lCode)]);
 
    cdsData.Data := ComServer.DBManager.Execute(lSQL);
  finally

  end;
end;
 
begin
  if SameText(EditingField, 'ItemCode') or

     try
       GetStockInfo;
       if Dataset.FindField('UOM').AsString = 'PCS' then
         Dataset.FindField('UDF_Price').AsFloat := cdsData.FindField('UDF_PCS').AsFloat else
       if Dataset.FindField('UOM').AsString = 'CTN' then
         Dataset.FindField('UDF_Price').AsFloat := cdsData.FindField('UDF_CTN').AsFloat else
         Dataset.FindField('UDF_Price').AsFloat := 1;
 
       Dataset.FindField('UnitPrice').AsFloat := Dataset.FindField('UDF_Price').AsFloat *
                                                 Dataset.FindField('UDF_Rate').AsFloat;

Avoid update the same existing field name Unit Price and "Rate". You have to create different name ie. UDF_Price and UDF_Rate.

Result Test

01. Go to Stock | Maintain Stock Item...

02. Edit the "ANT" stock item.

03. Insert additional UOM with different RATE, eg. 1 CARTON = 12 UNITS and 1 BOX = 60 UNITS.

04. Create new sales invoice from Sales | Invoice...

05. Call out the columns name UDF_mUnitPrice and Rate.

06. Insert and select the item code "ANT".

07. Change the UOM to CARTON. Rate will be changed to 12.

08. Input the value into UDF_mUnitPrice. U/Price will be calculated from your DIY script formula (UDF_mUnitPrice x Rate).
