## Re: purpose of pick and match.

In simple words your expression is doing this:

if Status is Assigned or In Progress or Pending then age = Today() - [Submit Date]

if Status is Canceled or Closed or Resolved then age = [Resolved Date] - - [Submit Date]

## Re: purpose of pick and match.

Vinay I think the purpose of using Pick and Match together is to simplify long if statements. For example

If(ABC = 'A', 1st Expression, If(ABC = 'B', 2nd Expression, 3rd Expression) can be simplified if done this way:

Pick(Match(ABC, 'A', 'B', 'C'), 1stExpression, 2ndExpression, 3rd Expression)

Here we only had 3 if statement, but if we have 10 then pick makes it really easy to read and understand from somebody who is trying to understand what is going on in the expression.

## Re: purpose of pick and match.

can you please tell me how this is working..

floor(pick(Match(Status, 'Assigned', 'Canceled', 'Closed', 'In Progress', 'Pending', 'Resolved'), today(), [Resolved Date], [Resolved Date], today(), today(), [Resolved Date]) - [Submit Date]) as age

## Re: purpose of pick and match.

Hi,

yes, exactly. Imagine you have a very long formula made up of, say, seven nested IF_clauses. That makes for a pretty complicated and long formula and a lot of opening brackets which are to be closed only at the very end of it all.

=> With PICK(MATCH()), it is much easier because every line of the formula (every MATCH, equivalent of one IF_part)
has its own pair of brackets. That much reduces the potential for errors in the formula.

1. Match : Match will give you a position number for serch string object.

E.x. Match('B','A','B','C') = 2

2. Pick : Pick will give you a search object as per the position number.

E.x. Pick(1,'A','B','C') = A

Easier way to write the above expression would be to do this:

If(Match(Status, 'Assigned', 'In Progress', 'Pending',), Today(), [Resolved Date]) - [Submit Date] as Age

Note: Assuming that Status can only take the given 6 values.

Hi,

i have an expression like following

=if(([Flip by Source No_]=1 AND [Flip by Business Line]=0 AND [Flip by Company]=0 AND [Flip by IC Partner]=0 AND [Flip by VAT Bus_ Posting Group]=0), //condn 1 source NO

if([Balance Flip Sign]=1,

if(AGGR(nodistinct sum(distinct [Additional Currency Amount]),[GL account code],[Source No_])<0, [Flipping Account No_],[GL account code]),

//else

if(AGGR(nodistinct sum(distinct [Additional Currency Amount]),[GL account code],[Source No_])>0, [Flipping Account No_],[GL account code])

),

//else condn 2

if(([Flip by Source No_]=0 AND [Flip by Business Line]=1 AND [Flip by Company]=0 AND [Flip by IC Partner]=0 AND [Flip by VAT Bus_ Posting Group]=0), //condn 2 Business Line

if([Balance Flip Sign]=1,

if(AGGR(nodistinct sum(distinct [Additional Currency Amount]),[GL account code],[Business Line])<0, [Flipping Account No_],[GL account code]),

//else

if(AGGR(nodistinct sum(distinct [Additional Currency Amount]),[GL account code],[Business Line])>0, [Flipping Account No_],[GL account code])

),

//else condn 3

if(([Flip by Source No_]=0 AND [Flip by Business Line]=0 AND [Flip by Company]=1 AND [Flip by IC Partner]=0 AND [Flip by VAT Bus_ Posting Group]=0), //condn 3 Company

if([Balance Flip Sign]=1,

if(AGGR(nodistinct sum(distinct [Additional Currency Amount]),[GL account code],[Entity Name])<0, [Flipping Account No_],[GL account code]),

//else

if(AGGR(nodistinct sum(distinct [Additional Currency Amount]),[GL account code],[Entity Name])>0, [Flipping Account No_],[GL account code])

),

//else condn 4

if(([Flip by Source No_]=0 AND [Flip by Business Line]=0 AND [Flip by Company]=0 AND [Flip by IC Partner]=1 AND [Flip by VAT Bus_ Posting Group]=0), //condn 4 IC Partner

if([Balance Flip Sign]=1,

if(AGGR(nodistinct sum(distinct [Additional Currency Amount]),[GL account code],[IC Partner Code])<0, [Flipping Account No_],[GL account code]),

//else

if(AGGR(nodistinct sum(distinct [Additional Currency Amount]),[GL account code],[IC Partner Code])>0, [Flipping Account No_],[GL account code])

),

//else condn 5

if(([Flip by Source No_]=0 AND [Flip by Business Line]=0 AND [Flip by Company]=0 AND [Flip by IC Partner]=0 AND [Flip by VAT Bus_ Posting Group]=1), //condn 5 VAT BUS

if([Balance Flip Sign]=1,

if(AGGR(nodistinct sum(distinct [Additional Currency Amount]),[VAT Bus_ Posting Group])<0, [Flipping Account No_],[GL account code]),

//else

if(AGGR(nodistinct sum(distinct [Additional Currency Amount]),[VAT Bus_ Posting Group])>0, [Flipping Account No_],[GL account code])

),)))))

How am I supposed to put these in pick match function?
