Deleting data from Data Buffer(import/Export from data buffer)

[Former Member]

Hello Experts,

I am using following Statement for passing data between two BSP pages,

DATA: xcookie TYPE xstring.

EXPORT it_item FROM it_item TO DATA BUFFER xcookie.

and importing same data using

IMPORT it_item = it_item FROM DATA BUFFER xcookie.

My problem is next time this import statement gets the old data i want to delete data from data buffer.

can anybody tell me how to delete data ftom data buffer.

Thanks in advance.

Hi Paresh,

You can use on of those lines:

• DELETE FROM { {MEMORY ID id}
  
• FREE MEMORY ID id.

Hi Jonathan,

As Xcookie is of type string it is giving me error as id should be of type C

Hi Paresh,

You can take a look at the include "RHESS00REP01" where they store a xstring into memory.

If your system is unicode this have an impact.

If you want to clear you xstring, you can also update an initial one...

Hi Jonathan,

I am storing internal table to data buffer xcookie.

xcookie is of type string.

i want to clear data buffer after each import. Other Wise it takes data which has been stored last time.

EXPORT it_item FROM it_item TO DATA BUFFER xcookie.

IMPORT it_item = it_item FROM DATA BUFFER xcookie.

i want to clear data in data buffer xcookie.

Hi,

you can use free or delete.

CLEAR dobj [ {WITH val [IN {CHARACTER|BYTE} MODE] }

  | {WITH NULL} ].

DELETE FROM MEMORY ID id.
