Sql statement, internal table

Question

<i>This is a simplified example of the problem:</i>
types: begin of t_MaterialStruct,
X_MARC_MATNR type MARC-MATNR,
X_MARC_WERKS type MARC-WERKS,
X_MBEW_VERPR type MBEW-VERPR,
end of t_MaterialStruct.
data: i_MaterialTab type table of t_MaterialStruct with header line.
The above table is partly filled with data.
It's missing the X_MBEW_VERPR.
Is it possible to update my internal table in a new  select statement or ?
Something like this:
select VERPR from MBEW into  i_MaterialTab where BWKEY = 3100

Hello Martin,
When you say that the above table is <i>partially</i> filled with data, are you referring to the partiality of the rows or of the columns?
Case 1 : If the internal table already has, let us say, some 10 records, you can certainly add new records to the internal table using the syntax :
SELECT VERPR
  FROM MBEW
  APPENDING CORRESPONDING FIELDS OF i_MaterialTab
WHERE BWKEY = 3100.
Case 2 : If the internal table has, for example 10 rows, but none of these rows has the X_MBEW_VERPR fields populated, then neither is it possible , nor does it technically make sense to populate this field in the 10 rows using another SELECT statement. That is beacuse, the SELECT statement might return more than 10 rows as the result. Also, the data fetched by the SELECT statement might not be consistent with the rest of the fields' data in those 10 rows.
Hope the explanation has been clear enough. If not please get back. If yes, then please mark the question as answered.
