Index Property for a nested For Loop in Data Transform
Dear Team,
I am facing an issue in getting the pyForEachCount for the Inner For Loop in a data transform which I need for a duplicate check logic.
Let me explain my requirement. I have a list of more than 30 offers and this list size can increase or decrease. All the offers are different.
I have to capture 10 random and unique offers in another Page List. I have written a custom function for the Random Number generation which takes a range and generates the random number. I am iterating through the D_OfferList which is loaded with all the offer details.
But I am stuck in the duplicate check logic. I have tried something but at the set step( Proprietary information hidden.1) of the inner For Loop I want to decrease the value of the pyForEachCount of the outer loop by 1. On Running the above DT, I am able to get 10 offers but some are repeated, hence the duplicate check is not working.I am not sure how to get hold of the index of the outer loop.
I have enclosed the screenshot of the data transform also.
Please help and suggest what other ways can this be handled.

You can use IsInPageList RUF to identify the duplicate entry in a list. And for exiting the iteration, use LengthOfPageList.

In step 1.1 use @(Pega-RULES:Utilities).IsInPageList("Test offer", .OfferID, Primary.OfferIndexList) function to check the OfferIndexList has the value, If no then continue to next steps else ignored and move to next iteration of D_OfferList.pxResults.
