Solved: Preceding load on peek() tables - Page 2 - Qlik Community

Vegar · ‎2019-04-18

I notice strange behaviour when performing a preceding load on a table generated using the peek function? Can anyone explain what's happening and why? @hic do you have an explanation?

Example 1. Not using preceding load, the peek works at intended. On the Version 3 ValidTo I get the version 4 ValidFrom figures.


Data:
LOAD 
  rowno() as Id, 
  * inline [
Version, Location,	ValidFrom
3,	Uppsala,	2019-04-18
3,	Storvreta,	2019-04-18
3,	Tierp,		2019-04-18
4,	Uppsala,	2019-04-19
4,	Storvreta,	2019-04-19
4,	Tierp,		2019-04-19
];

PeekTable:
LOAD
  Id, 
  Version,	
  Location,	
  ValidFrom,
  If(peek('Location')=Location, peek('ValidFrom'), '9999-12-31') as ValidTo
Resident Data
ORDER BY Location, Version desc;

DROP TABLE Data;

Example 2. Adding preceding load

But if I add a preceeding load to my my peek table something strange happens.... all ValidTo ends up as 9999-12-31.Output using preceding load on peek

Data:
LOAD 
  rowno() as Id, 
  * inline [
Version, Location,	ValidFrom
3,	Uppsala,	2019-04-18
3,	Storvreta,	2019-04-18
3,	Tierp,		2019-04-18
4,	Uppsala,	2019-04-19
4,	Storvreta,	2019-04-19
4,	Tierp,		2019-04-19
];

Peek:
LOAD 
  Id, 
  ValidTo
;
PeekTable:
LOAD
  Id, 
  Version,	
  Location,	
  ValidFrom,
  If(peek('Location')=Location, peek('ValidFrom'), '9999-12-31') as ValidTo
Resident 
  Data
ORDER BY Location, Version desc;

//DROP TABLE Data;

My workaround

Data:
LOAD rowno() as Id, * inline [
Version, Location,	ValidFrom
3,	Uppsala,	2019-04-18
3,	Storvreta,	2019-04-18
3,	Tierp,		2019-04-18
4,	Uppsala,	2019-04-19
4,	Storvreta,	2019-04-19
4,	Tierp,		2019-04-19
];

PeekTable:
LOAD
  Id, 
  Version,	
  Location,	
  ValidFrom,
  If(peek('Location')=Location, peek('ValidFrom'), '9999-12-31') as ValidTo
Resident Data
ORDER BY Location, Version desc;

Final:
LOAD 
  Id, 
  ValidTo
Resident PeekTable
;
DROP Table PeekTable;

May be try this

	 Total_Purchase,
	 If(Customer_Name = Previous(Customer_Name), RangeMax(RangeSum(Peek('result'), -Customer_Sales), 0), Total_Purchase - Customer_Sales) as result;

But Sir, I'm using qvd except for an inline table because I have many data of the same. When Put the following into it. its descending order will be disturbed.

If(Customer_Name = Previous(Customer_Name), RangeMax(RangeSum(Peek('result'), -Customer_Sales), 0), Total_Purchase - Customer_Sales) as result;

this is my code.

CASH_ADJUSTED_TOTAL:
NoConcatenate
LOAD SLAB,
ELEMENT_ID,
ACCOUNT_NUMBER,
TARIFF_DEDUCTED,
CASH_BALANCE,
// RangeMax(RangeSum(Alt(Peek('result'), CASH_BALANCE), -Rangesum(TARIFF_DEDUCTED)), 0) as result;
If(ELEMENT_ID = Previous(ELEMENT_ID) and Previous(ACCOUNT_NUMBER) = ACCOUNT_NUMBER, RangeMax(RangeSum(Peek('result'), -TARIFF_DEDUCTED), 0), CASH_BALANCE - TARIFF_DEDUCTED) as result;

LOAD SLAB,
ELEMENT_ID,
ACCOUNT_NUMBER,
(SLAB & ELEMENT_ID & ACCOUNT_NUMBER) AS ORDER,
TARIFF_DEDUCTED,
SUM_TOTAL_AMOUNT,
MAX_SLAB,
If(STATUS = 'N' AND SLAB = MAX_SLAB, SUM_TOTAL_AMOUNT, 0) AS CASH_BALANCE,
If(STATUS = 'N', 'Y', 'N') AS STATUS

Resident CASH_DEPOSIT_TOTAL

Not sure I understand your concern?

I'm using qvd except for an inline table because I have many data of the same. its descending order and result are disturbed.

Whenever I used particular Element id and Account number, its provide correct result and perfect descending order.

CASH_ADJUSTED_TOTAL:
NoConcatenate
LOAD SLAB,
ELEMENT_ID,
ACCOUNT_NUMBER,
TARIFF_DEDUCTED,
CASH_BALANCE,
// RangeMax(RangeSum(Alt(Peek('result'), CASH_BALANCE), -Rangesum(TARIFF_DEDUCTED)), 0) as result;
If(ELEMENT_ID = Previous(ELEMENT_ID) and Previous(ACCOUNT_NUMBER) = ACCOUNT_NUMBER, RangeMax(RangeSum(Peek('result'), -TARIFF_DEDUCTED), 0), CASH_BALANCE - TARIFF_DEDUCTED) as result;

LOAD SLAB,
ELEMENT_ID,
ACCOUNT_NUMBER,
(SLAB & ELEMENT_ID & ACCOUNT_NUMBER) AS ORDER,
TARIFF_DEDUCTED,
SUM_TOTAL_AMOUNT,
MAX_SLAB,
If(STATUS = 'N' AND SLAB = MAX_SLAB, SUM_TOTAL_AMOUNT, 0) AS CASH_BALANCE,
If(STATUS = 'N', 'Y', 'N') AS STATUS

Resident CASH_DEPOSIT_TOTAL

result are disturbed? Can you show an image or a sample? I won't really know what disturbed means unless you provide more details

When open the qvd data, it has multiple record. I'm shocked that how to do it correct

somacdc · ‎2019-08-27

I resolved by myself 🙂

Thanks for your support earlier.
