@Asitabha Deb,
The issue is your use a quotes in how you're trying to build your VLOOKUP statement. In Blue Prism, a double quote is treated as the beginning of a string expression. Everything up to the next double quote is part of that string. The second double quote terminates the string and is the end of the expression unless you use the ampersand (&) to concatenate something additional to the expression. Also, if you need to embed double quotes in the string expression itself you have to use the Chr(34) function.
Try the following expression:
"=VLOOKUP(F2,'[" & Chr(34) & "DID " & FormatDateTime(Today(),"dd.MM.yyyy") & ".xlsx" & Chr(34) & "]Sheet1'!$A$2:$D$22,4,0)"
