MDG-M: storing of 'material description' during runtime

hi everybody,

I don't understand how the material description is stored in the change request context during runtime.

There's the attribute TXTMI in entity MATERIAL. but how does MDG store multiple entries for material description?

assumed there are 2 descriptions: one in english and one more in spanish. how can i read and manipulate these cr-data?

I tried to read out the entity data with convenience api (method: READ_ENTITY_DATA). but then i just get one of the entries and no information regarding the key (language code). where is the combination of languagecode + description getting stored?

best regards,

Hannes
