Convert ITAB to XSTRING and back-CodePudding

I need to save an itab as an xstring or something like this and save it in dbtab. Later I need to gather this xstring from dbtab and convert it in the itab before with exactly the same input from before.

I tried a lot of fuba´s like: SCMS_STRING_TO_XSTRING or SCMS_XSTRING_TO_BINARY but I didn´t find something to convert it back.

Does somebody have tried something like this before and have some samples for me ?

Unfortunately I didn´t find something on other blogs or else.

CodePudding user response：

use

import ... from data buffer

and

export ... to data buffer

to (re)store any variable as xstring.

Or you can use

import|export ... from|to database ...

I did some methods to do this:

First I loop at the table and concatenate it into a string. Then convert the string into an xstring.

 LOOP AT IT_TABLE ASSIGNING FIELD-SYMBOL(<LS_TABLE>).
CONCATENATE LV_STRING <LS_TABLE> INTO LV_STRING SEPARATED BY CL_ABAP_CHAR_UTILITIES=>NEWLINE.
ENDLOOP.
CALL FUNCTION 'SCMS_STRING_TO_XSTRING'
    EXPORTING
      TEXT   = IV_STRING
    IMPORTING
      BUFFER = LV_XSTRING.

Back would be like: Convert xstring back to string String into table

 TRY.
    CL_BCS_CONVERT=>XSTRING_TO_STRING(
        EXPORTING
          IV_XSTR   = IV_XSTRING
          IV_CP     =  1100                " SAP character set identification
        RECEIVING
          RV_STRING = LV_STRING
      ).
  CATCH CX_BCS.
ENDTRY.

SPLIT IV_STRING AT CL_ABAP_CHAR_UTILITIES=>NEWLINE INTO: TABLE <LT_TABLE> .

READ TABLE <LT_TABLE> ASSIGNING FIELD-SYMBOL(<LS_TABLE>) INDEX 1.
IF <LS_TABLE> IS INITIAL.
  DELETE TABLE <LT_TABLE> FROM <LS_TABLE>.
ENDIF.
