Partial Reload of Last N Months: not finding table

[jeanful]

Hello experts, I have a table called Sales, which is fully loaded from Excel file.

I would perform a partial reload of the data of this table. The loading logic would be that only the last N months are updated. So, I'm simulating that the last N months come from inline table.

So the script should have:
- Full loading: all data is read from the excel
- Partial loading: only last N months are updated (from inline table).

This is the script I created. When launching partial reload, Qlik Sense Cloud says that the Sales table is not found. Why?

[Sales]:
LOAD
	[ANNO],
	[MESE],
	[CLIENTE],
	[PRODOTTO],
	[QTA]
 FROM [lib://xxx/File1.xlsx]
(ooxml, embedded labels, table is Foglio1);


If IsPartialReload() Then

  [Sales]:
  LOAD * FROM [lib://xxx/TestDelta3M.qvd](qvd) where [MESE] <= Num(Month(Now()))-3;

  //Delta last N months
  [T_DELTA]:
  ADD LOAD *
    INLINE [
    ANNO, MESE, CLIENTE, PRODOTTO, QTA

    ];
    
    Concatenate([SALES])
    ADD LOAD *
    RESIDENT T_DELTA;

EndIf;

STORE Sales INTO
[lib://xxx/TestDelta3M.qvd];

Here is the error:
Table 'SALES' not found The engine error code: Table not found error:11001 The error occurred here: Concatenate([SALES]) ADD LOAD * RESIDENT T_DELTA

Thank you!

Maybe

Qlik is case sensitive

You have SALES and Sales

Thank, its' going through now! But there's another problem: it does not find the T_DELTA table when executing the following instruction:

    Concatenate([SALES])
    ADD LOAD *
    RESIDENT T_DELTA;

 How can I concatenate delta rows into the full table from the qvd?

Thanks a lot!
