free memory id 'SAPLSTXD'

Hi,

I am using

CALL FUNCTION'READ_TEXT'

to read different texts from database.

I am inside a BADI and when I call READ_TEXT at that time system returns the run time value of text, but I want to get the value of text from database table.

When I use "free memory id 'SAPLSTXD'" - its workig fine but the problem with this statement, it deletes all the texts which user has changed on runtime and the updated texts changed by the user are not saved then.

Is there any way that I can free the memory of some specific text types rather than all?

OR

Is there any way that when I call read_text FM, system force it to get the value from database table instead of memory?

Thanks,
