Power query

1st create a custom column:  if the column11(K) is null then take the value of the column1(A). 

2nd select the created custom column and fill down

3rd filter the column2(B) keeping only the cells needed: as seen you must filter the cells with "IN" value.

Rename the columns as needed:

Column1(A)--> DocNumber;

Column2(B)-->TypeOfDoc;

Custom-->Amount

I hope this helps, if so, please mark as solution. Kudos are welcome
