Hi Vaibhav,
The Text table for material master is table MAKT.
Field MAKT-MAKTX contains the material description and can be read based on MATNR & SPRAS.
You need to have this field in your BRF+ design so that data can be fetched and used.
If you are looking for something else then post more details about your requirement and how BRF+ is used in your scenario.
