I am trying to generate an arrayformula for the whole column but it does not work, when I use the same formula cell by cell, it generates correct value. Here is the formula for F1
cell:
=if(Iferror(vlookup($D1, INDIRECT("$"&"A"&MATCH(E1,$B:$B,0)+1&":$B"),2,false),"")=E1,"",Iferror(vlookup($D1, INDIRECT("$"&"A"&MATCH(E1,$B:$B,0)+1&":$B"),2,false),""))
I am trying to convert it into ArrayFormula like this and put it in F1
:
=ARRAYFORMULA(if(Iferror(vlookup($D:$D, INDIRECT("$"&"A"&MATCH($E:$E,$B:$B,0)+1&":$B"),2,false),"")=$E:$E,"",Iferror(vlookup($D:$D, INDIRECT("$"&"A"&MATCH($E:$E,$B:$B,0)+1&":$B"),2,false),"")))
But this does not work and returns empty column, here is the sheet if you want to test it, you can find formula in column F:

Please share your knowledge how to go about it as I am trying to learn formulas starting from basic level? Thank you.

Unclear of the full scope but from your expected result scenario(in Column F) you seem to be pulling off second match(if any). well in that case try:
=BYROW(D:D,LAMBDA(dx,IF(dx="",,IFNA(FILTER(ARRAY_CONSTRAIN(FILTER(B:B,A:A=dx),2,1),{0;1})))))

when working with more than one condition, you can usually use FILTER for it. In this case, I used MAP to refer to both columns D and E, and used FILTER to narrow to the matches in A column, and then to those values that were further than the row of the MATCH of E value. Then, with INDEX I chose the first value of that resulting range.
=MAP(D:D,E:E,LAMBDA(d,e,IFERROR(IF(d="","",INDEX(FILTER(B:B,A:A=d,ROW(B:B)>MATCH(e,B:B,0)),1)))))
