Write.table in R-script modify text column

I have a r-Script in powerbi report in order to save big table to .csv file (1-2 mln records): One of a column in this table (MOMENT) is timestamp with milliseconds in text format - 20200227100000001.

Original table

Here is the script:

write.table(dataset,"SomePath",  quote = FALSE, sep = "","",row.names = FALSE)

But when I use R-Script it writes this column as a number - 2.02002E+16. I've added formaing to this column:

dataset$MOMENT <- format(dataset$MOMENT,scientific = FALSE) 
write.table(dataset,"SomePath",  quote = FALSE, sep = "","",row.names = FALSE)

But now the R-Script randomly round the value in column MOMENT - instead of 20200227100000001, 20200227100000002, 20200227100000003 I get 20200227100000000After R-Script

I tried another option like paste, paste0 - non of them resolve the issue.

It looks like R-script works correctly. I tried to reproduce the error in R- Studio and if I input dataset manually the script writes the file correctly. But when I output original dataset from Power BI into R-Studio I get the following

dataset
    #SYMBOL VOLUME      ID_DEAL       MOMENT PRICE SYSTEM TYPE
1   BR53BC0      1 2.570967e+13 2.020023e+16  2.12   5986    B
2   BR53BO0      1 2.570967e+13 2.020023e+16  2.86   5986    B
3   BR53BO0      1 2.570967e+13 2.020023e+16  2.88   5986    B
4   BR53BO0      2 2.570967e+13 2.020023e+16  2.88   5986    B
5   BR53BO0      2 2.570967e+13 2.020023e+16  2.88   5986    B
6   BR53BO0      3 2.570967e+13 2.020023e+16  2.50   5986    B
7   BR53BO0      5 2.570967e+13 2.020023e+16  2.66   5986    B
8   BR53BO0      5 2.570967e+13 2.020023e+16  2.77   5986    B
9   BR53BO0     10 2.570967e+13 2.020023e+16  2.65   5986    B

Power BI shows columns ID_DEAL and MOMENT as "text" but in reality they are numbers

How can I get proper value in .csv file?
