    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

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
