Hi, I am creating a query for a Virtual Cube, it has only one infoobject and it has been configured as Dircect Acces

No master data, no texts.
I use it in a query as filter, but every time a set a value (its values are 'X' and empty) an error is shown, indicating that de paremeter does not have master data.
The idea is to pass this value to the extractor.
I have created its variable in different ways: manual, customer_exit, without context.
Thansks in advance.
