In Spanish: El prefijo de columna 'recumat_htor2.dbo.alm_und_consumos' no coincide con un nombre de tabla o con un alias usado en la consulta

"My" translation: The column's prefix 'recumat_htor2.dbo.alm_und_consumos' doesn't match with a table's name or an alias used in the query

This DB and this table works without problem in another WebForm using EntityCollection (not TypedList)

The line code is:

adapter.FetchTypedList(pedidos.GetFieldsInfo(), pedidos, filter,0,Sorter, false);

Be sure you base your filter on the RelationPredicateBucket you get back from peridos.GetRelationInfo().

Exactly! That was the problem, thank you again!
