Delete rows based on calculated number

SoufTC — Tue, 14 Jun 2022 07:06:18 GMT

I’m having trouble to delete rows based on calcluted # number.

I have 3 tables.

1. A table that defines unique list of call (call)[List] per day (call)[Date]. each call has an answer status (call)[Status]. I created a column to have a unique field (call)[Key]

Call which appears as following :

| List | Status | Date | Key

-------------------------------------------------------------

| List1 | A | 2022-02-09 | List1 2022-02-09

| List1 | DO | 2022-02-09 | List1 2022-02-09

| List2 | A | 2022-02-09 | List2 2022-02-09

| List2 | DO | 2022-02-09 | List2 2022-02-09

| List3 | A | 2022-02-09 | List3 2022-02-09

| List3 | DO | 2022-02-09 | List3 2022-02-09

| List1 | C | 2022-02-10 | List1 2022-02-10

| List2 | A | 2022-02-10 | List1 2022-02-10

| List2 | DO | 2022-02-10 | List1 2022-02-10

| List2 | A | 2022-02-10 | List1 2022-02-10

| List3 | DO | 2022-02-10 | List1 2022-02-10

| List3 | A | 2022-02-10 | List1 2022-02-10

2. A table a repository Status (Status )[Names] and (Status)[Status]; The join with the (Call)table is done with the (Status)[Status]

Status which appears as following :

| Names | Status |

-----------------------------

| answer | A |

| drop out | DO |

| cancel | C |

2. A table Number with a calculated column (Number)[#drop] ; The join with the (Call)table is done with the (Call)[Key]

Number which appears as following :

| Key | # drop |

-------------------------------------

| List1 2022-02-09 | 2 |

| List2 2022-02-09 | 2 |

| List3 2022-02-09 | 1 |

| List1 2022-02-10 | 0 |

| List2 2022-02-10 | 1 |

| List3 2022-02-10 | 1 |

I want to create a new table called NewDF by deleting the rows based on (Number)[#drop] and with (Status )[Names] = "drop out"

Desired result is the following:

| List | Status | Date | Key

-------------------------------------------------------------

| List1 | A | 2022-02-09 | List1 2022-02-09

| List1 | DO | 2022-02-09 | List1 2022-02-09

| List2 | A | 2022-02-09 | List2 2022-02-09

| List3 | A | 2022-02-09 | List3 2022-02-09

| List3 | DO | 2022-02-09 | List3 2022-02-09

| List1 | C | 2022-02-10 | List1 2022-02-10

| List2 | A | 2022-02-10 | List1 2022-02-10

| List3 | A | 2022-02-10 | List1 2022-02-10

Please, any help?

Thank's in advance

SoufTC I'm missing what logic do you want to get from the KEY / # Drop table.
I wrote for now this:

Calc Table = FILTER( FactCalls, RELATED(DimStatus[Names]) <> "drop out" )

Just add why the DO in your result are still there after the removal and I'll add the logic

SpartaBIthank's for your response. from the table Number we define how many rows to delete according to the (Number)[#drop]: for example according to Table Number for the (Call)[Key] = List1 2022-02-09 we have (Number)[#drop] = 2 rows to delete. In (call)[List] we have 3 rows = DO so we keep delete 2 and keep 1. I don't know if clear enough thank's in advance

SoufTC this was super super tricky.
Also, you had mistakes in your tables you copied (look at the first table you pasted), so make sure you test this with accurate data.
Attaching the file:
Delete Rows.pbix
It involved extra neccesary steps in Power Query so make sure you follow them and then I could have written this calculated table:

Calc Table = VAR _tbl1 = SELECTCOLUMNS( FILTER( ADDCOLUMNS( FactCalls, "@Removal Index", IF( RELATED(DimStatus[Names]) <> "drop out", 0, RANKX(FILTER(FactCalls,FactCalls[Key] = EARLIER(FactCalls[Key])), FactCalls[Index], ,ASC) - COUNTROWS(FILTER(FactCalls, FactCalls[Status] <> "DO" && FactCalls[Key] = EARLIER(FactCalls[Key]))) ) - RELATED(DimDrops[# drop]) ), [@Removal Index] < 0 ), "List", [List], "Status", [Status], "Date", [Date], "Key", [Key] ) RETURN _tbl1
