Create a New Table using the code below, which will include all combinations

New Table = CROSSJOIN( vm,Software )

Add the following Column to it to identify missing combination:

Missing = IF( ISEMPTY( FILTER( user, User[VM Name]=EARLIER('New Table'[VM Name]) && User[Software Installed] = EARLIER('New Table'[Sofware Names]) ) ), "MISSING")

Anonymous - Not entirely sure of the ask here, LOOKUPVALUE maybe?

Anonymous , this will give you a new table

except(crossjoin(all(Table1[VM Name]), selectcolumns(Table2,"Software Installed",Table2[Sofware Names])),Table3)

for except you need same name across tables

Fowmy It Helps .. Can I also pick more columns from User table based on VM name in the new table created ?.

User table has User details for each VM . This would help in plotting the data

Yes sure,

The 1st code will work without any change.

You can modify the 2nd code which adds the column. You can add more fileds starting with && as I did for Software Installed in the following

Missing = IF( ISEMPTY( FILTER( user, User[VM Name]=EARLIER('New Table'[VM Name]) && User[Software Installed] = EARLIER('New Table'[Sofware Names]) ) ), "MISSING")

Let me know if you face any issue

Fowmy I tried but that is not adding a new column as there is a Many to Many cardinality setup .

VN name can be duplicate in both the tables .

For Eg User table has additional columns like User name, Email ID , Company timestamp etc . I want to add these fields in New table created for ploting the visuals Or is there any other method to use these directly in visuals.

Graphs like for list of VMs these software are missing and Owner details .

Fowmy Sharind the sample data as the compelte data set is big with many fields

I want to plot the visuals on how many VMs are missing which softwares .Also some other graphs on subscriptin ID and other criterias based on data set .

1. Distinct VM is coming from a different table as that has the complete inventory of the VMs as there could be some VM missing in User table as well ideally which have no Software installed at all.

2. Distinct softwares I am taking from the user Table itself for finding all permutation and combinations . (as User table only shows the Installed sotware not the missing ones)

3. We can create a new table as well like the output table or if the details can be added on the user tabel itself that would also work as it will help in plotting other graphs.

Please suggest on how can I achieve this , tried with many ways however unfortunately couldnot succeed

Distinct VM Table	Distinct Software Table	User Table
VM Name	Sofware Names	VM Name	Software Installed	Ower	Email	Subscription ID
VM 1	Software 1	VM 1	Software 2	a	a@xyz.com	x
VM 2	Software 2	VM 2	Software 1	b	b@xyz.com	y
VM 3	Software 3	VM 3	Software 1	c	c@xyz.com	z
VM 4	Software 4	VM 3	Software 2	c	c@xyz.com	z
		VM 3	Software 3	c	c@xyz.com	z

Desired Output

VM Name	Sofware Names	Owner	Email	Subscription ID	Status
VM 1	Software 1	a	a@xyz.com	x	Missing
VM 1	Software 2	a	a@xyz.com	x	Installed
VM 1	Software 3	a	a@xyz.com	x	Missing
VM 1	Software 4	a	a@xyz.com	x	Missing
VM 2	Software 1	b	b@xyz.com	y	Installed
VM 2	Software 2	b	b@xyz.com	y	Missing
VM 2	Software 3	b	b@xyz.com	y	Missing
VM 2	Software 4	b	b@xyz.com	y	Missing
VM 3	Software 1	c	c@xyz.com	z	Installed
VM 3	Software 2	c	c@xyz.com	z	Installed
VM 3	Software 3	c	c@xyz.com	z	Installed
VM 3	Software 4	c	c@xyz.com	z	Missing
VM 4	Software 1	NA	NA	NA	Missing
VM 4	Software 2	NA	NA	NA	Missing
VM 4	Software 3	NA	NA	NA	Missing
VM 4	Software 4	NA	NA	NA	Missing

Fowmy Greg_Deckler any help here please . Can this be achieved

Anonymous - Probably. See attached PBIX below sig, Tables (29), (29a), (29b), (29c). 29c is the output.

Table (29c) = ADDCOLUMNS( GENERATE('Table (29)','Table (29a)'), "Owner",LOOKUPVALUE('Table (29b)'[Ower],[VM Name.1],[VM Name],"NA"), "Email",LOOKUPVALUE('Table (29b)'[Email],[VM Name.1],[VM Name],"NA"), "Subscription ID",LOOKUPVALUE('Table (29b)'[Subscription ID],[VM Name.1],[VM Name],"NA"), "Status",IF(COUNTROWS(FILTER('Table (29b)',[VM Name.1]=[VM Name]&&[Software Installed]=[Software Names]))>0,"Installed","Missing") )

Turned out to be a lot of LOOKUPVALUE after all.

Greg_Deckler Thanks .It worked 🙂

Can we also do this in same table (29B) instead of a new table creation .

Anonymous - I do not believe so. If you want a full inventory you have to kind of "blowout" the table into more rows than you have in any of the base tables.
