Datastore/extractors: View Data --> Two filds are blank

Dear all:

we are using extractors as source (Data Services).

We have some additional fields added to  2LIS_13_VDITM datasource

Fashion Brand (char 3)

Partner_YA (char 10)

Document Number (char 10)

Their value come from CMOD.

If I check the extraction using RSA3 in ECC I get data for all these additional
fields.

Data Services gets data for only one field (Fashion Brand);  the other two (Partner_YA, Document Number)
are <null>.

Does anyone know the reason for this strange behaviour?

Thanks everybody.
