Looping in a Daily Dim

Hello,

i try to create a TI Loop that goes through all Days in a specific year (Day is the Element Level 0), in the loop i will do some calulations and write back the result in a cell at this day.

I think i have to create a subset and loop through the subset, would be nice if someone has a snipped from something like that (create subset an loop through it), i cant find any information in Google, or i'm just bad at google search.

Thanks for your help!

Hi,

a short idea what do to. You have finalise by yourself.

Take a look here

https://www.bihints.com/book/export/html/68
this gives you all N elements of a parent
{TM1FILTERBYLEVEL({DESCENDANTS(Product.[Customer Lending]) }, 0)}

https://www.ibm.com/support/knowledgece ... tsize.html
SubsetGetSize - lets u know the number of elements in a subset

https://www.ibm.com/support/knowledgece ... tname.html
SubsetGetElementName - gives the element by index

the loop

i=0;
numElem = SubsetGet.....
while(i<=numElem);
sElem = SubsetGetElementName(DIm, Subset, i)

Do whatever you want

i=i+1;
end;

Best regards
orlando

Awesome! Thank you so much!

I will post my code after i'm done!

Now i got a additional question, i set up my loops and calculation but if i trace the loop via ASCIIOUTPUT i see that its just looping the inner While and not the others..


i Build the Loops like:

Code: Select all

While(x <= y);

	do something
	
	while(c <= d);
		do something else
	end;

end;
Just the while(c <= d); loops correct. Is it not the correct syntax?

Thanks and KR

think so, could you post the original code?

Hey Orlando, got my mistake, forgot to set the counter in the inner loops back to 1 thats why the loop just run once.

Here is my prolog script:

Code: Select all


#****Begin: Generated Statements***
#****End: Generated Statements****



#pFilter = 'Jahre: '|pJahr|' & Version: '|pQuellversion;

#build subsetname
sSubsetName = 'tmpCappingCalc_TI_' | today(1);


nProdCap = pProdCap \ 100;

#create tmp Subsets

if(SubsetExists('Tag', sSubsetName) = 1);
  SubsetDestroy('Tag', sSubsetName);
EndIf;
if(SubsetExists('Kontaktart', sSubsetName) = 1);
  SubsetDestroy('Kontaktart', sSubsetName);
EndIf;
if(SubsetExists('MA-Pool', sSubsetName) = 1);
  SubsetDestroy('MA-Pool', sSubsetName);
EndIf;

SubsetCreatebyMDX(sSubsetName, '{TM1FILTERBYLEVEL({DESCENDANTS(Tag.['|NumberToString(pJahr)|']) }, 0)}');
SubsetCreatebyMDX(sSubsetName, '{TM1FILTERBYLEVEL({DESCENDANTS(Kontaktart.[Kontaktarten Gesamt]) }, 0)}');
SubsetCreatebyMDX(sSubsetName, '{TM1FILTERBYLEVEL({DESCENDANTS([MA-Pool].[MA-Pool Gesamt]) }, 0)}');


#count elements in subsets
numEl = SubsetGetSize('Tag', sSubsetName);
kontaktArtsize = Subsetgetsize('Kontaktart', sSubsetName);
maPoolSize = Subsetgetsize('MA-Pool', sSubsetName);
peSize = Subsetgetsize('Planungseinheit', 'Alle n Level');

dayi = 1;
kontaktArtIndex = 1;
maPoolIndex = 1;
peIndex = 1;

#Loop all elements in Subset
while(dayi<=numEl);
  #get element name from index
  sDay = SubSetGetElementName('Tag', sSubsetName,dayi);
  
  while(kontaktArtIndex <= kontaktArtsize);
    sKontaktArt = SubsetGetElementName('Kontaktart', sSubsetName, kontaktArtIndex);
    while(maPoolIndex <= maPoolSize);
      sMaPool = SubsetGetElementName('MA-Pool', sSubsetName, maPoolIndex);
        while(peIndex <= peSize);
          sPE = SubsetGetElementName('Planungseinheit', 'Alle n Level', peIndex);
          
          nErlangMenge = CellGetN('Blending_Simulation', sDay, pVersion, sMApool, sPE, sKontaktArt, 'ErlangC Menge Lmin');
          nSonstigeMenge = CellGetN('Blending_Simulation', sDay, pVersion, sMApool, sPE, sKontaktArt, 'sonstige Menge Lmin');
          nBlendingMenge = CellGetN('Blending_Simulation', sDay, pVersion, sMApool, sPE, sKontaktArt, 'blending Menge Lmin');

          nErlangRMA = CellGetN('Blending_Simulation', sDay, pVersion, sMApool, 'Leistungsspektrum', sKontaktArt, 'Erlang rMA');
          nNichtGeblendeteRMA = CellGetN('Blending_Simulation', sDay, pVersion, sMApool, 'Leistungsspektrum', sKontaktArt, 'nicht geblendete rMA');
          nNochNichtGeblendeteRMA = CellGetN('Blending_Simulation', sDay, pVersion, sMApool, 'Leistungsspektrum', sKontaktArt, 'noch nicht geblendete rMA');
          nRmaProdCap = CellGetN('Blending_Simulation', sDay, pVersion, sMApool, 'Leistungsspektrum', sKontaktArt, 'noch nicht geblendete rMA');
          nGesamtRMA = nErlangRMA + nNichtGeblendeteRMA + nNochNichtGeblendeteRMA;
          
          prod = nMengeGesamt \ (nGesamtRMA * CellGetN('Blending_Simulation', sDay, pVersion, sMApool, sPE, sKontaktArt, 'Arbeitszeit in Min'));
          ASCIIOUTPUT('C:\Testo.txt',NumberToString(dayi), NumberToString(peIndex), sPE,'Day: ', sDay, sKontaktart, sMaPool, sPE, NumberToString(prod), NumberToString(nProdCap), 'ErlangMenge', NumberToString(nErlangMenge), 'nSonstigeMenge', NumberToString(nSonstigeMenge),'nBlendingMenge', NumberToString(nBlendingMenge) );
          While(prod > nProdCap);
            ASCIIOUTPUT('C:\Testo.txt', NumberToString(prod), NumberToString(nProdCap));

            CellPutN(CellGetN('Blending_Simulation', sDay, pVersion, sMApool, sPE, sKontaktArt, 'rmA Prod Capping')+0.5,'Blending_Simulation', sDay, pVersion, sMApool, sPE, sKontaktArt, 'rmA Prod Capping');
          end;
          peIndex = peIndex +1;
        end;
        peIndex =1;
      maPoolIndex = maPoolIndex +1;
    end;
    maPoolIndex = 1;
    kontaktArtIndex = kontaktArtIndex +1;
  end;
  kontaktArtIndex = 1;
  dayi=dayi+1;
end;

SubsetDestroy('Tag', sSubsetName);
SubsetDestroy('Kontaktart', sSubsetName);
SubsetDestroy('MA-Pool', sSubsetName);

Very bad code, i think its totally vs best practice but it works. :)

Thank you so much for your help!

Normally, you would set the counter in the loop to the initial value (1 here) before the WHILE statement.

Consider also using a cube view as the data source of the process, instead of looping 3 times. This can be very inefficient (not necessarily so but oftentimes it is).

Not the last time you will forget this.....

may be, but the code works - that is the most important thing.
now you can start with the optimization
