Report Books - If Statement

Question

Hi There,
I am trying to create a book with a loop on our UD4 (project). I have it working but I want to add an IF statement to filter out tabs that contain no data. Referencing a previous post, I tried adding an IF statement to filter out an account (A#TotSGA in our case). This is the statement I am using, but it doesn't seem to work.
XFCell(Cb#00_CorpRpt:E#7420:C#Local:S#Budget_V2:T#2024:V#Periodic:A#OtherSGA:F#EndBal:O#Top:I#Top:U1#Top:U2#Top:U3#Top:U4#|Loop1Variable|:U5#Top:U6#Top:U7#None:U8#None) &lt;&gt; 0.00
I have attached screenshots and referenced the previous topic below. Any help is appreciated!

Ha! An old post coming back to haunt me.&nbsp;
The way we do this now is through the use of a custom member list function that pulls a databuffer (which will only return where records exist).&nbsp; It's setup to work for Account and UD1-UD8.&nbsp; I know this method works since we actively use it in Report Books, although it can be deployed in CV's or QV's.
The custom function is below.&nbsp; Note, you'll need to set your sane defaults for the dimensions.&nbsp; I recommend you test how it works in a very basic QV before using it in your report book.&nbsp; When you're ready to use it in your report book, your loop type is Member Filter.

I added our default UDs. From Line 101, I was confused on what I needed to put there.
In addition, I'm not sure if I'm using the parameter string correctly. Here is one that I was testing in one of my Cube Views for UD4:
X#Member.CustomMemberList(BRName=XFR_MemberList_ByDataBuffer, MemberListName=MemberListHasData, MemberExpansion=[Base], Sort=[True|False], MaxNumOfMembers=[20], Cube=[00_CorpRpt], Entity=[|CVEntity|], Cons=[Local], Scenario=[Budget_V2], Time=[2024], UD4=[TotProject])
Any help would be appreciated. Thank you!

Hi anilpersaud: you're really close, just a few things to change and we can hopefully get this working for you.
Regarding the changes to the BR:

You only needed to modify the sections that indicated 'SET A DEFAULT HERE' which it looks like you've set correctly.

Modifications to make it work in your CV. For your member filter, try:
U4#TotProject.CustomMemberList(BRName=XFR_MemberList_ByDataBuffer, MemberListName=MemberListHasData, MemberExpansion=[Base], Sort=[True], MaxNumOfMembers=[20])
A few notes on the changes I made above:

The X#Member is meant to represent the dimension you are pulling and the initial starting member to expand from, in this case U4#TotProject
Sort, you'll want to pick either 'True' or 'False'
The rest of the dimensions can be removed when used in the CubeView as they&nbsp;will simply pull from what is defined in your Cube View POV.&nbsp; However, you can also retain them if you'd like the member list to generate from the unique dimensions you've referenced rather than following the Cube View POV.
General reminder, the rest of the dimensions will follow those defaults you've set, but can also be overridden as needed.

When you go to use this in a Report Book:

The Report Book does not have the concept of the Cube View POV, hence you&nbsp;will need to include those Data Unit dimensions in the syntax of the CustomMemberList
Usage in the Report Book Loop Member Filter will look like:

U4#TotProject.CustomMemberList(BRName=XFR_MemberList_ByDataBuffer, MemberListName=MemberListHasData, MemberExpansion=[Base], Sort=[True], MaxNumOfMembers=[20], Cube=[00_CorpRpt], Entity=[RealEntityHere-or-|!UseAnEntityParameter!|], Cons=[Local], Scenario=[Budget_V2], Time=[2024])

Let me know if that gets it going for you.
Cheers,&nbsp; &nbsp; -db
