Former Member — Wed, 10 May 2006 14:23:06 GMT

Hi,

Can this be done, I can read the value of a field in program A from program B using field symbols, but I need to update it.

Thanks

Is one calling the other? If so, I think you can do this with field symbols.

Martin,

As you have assigned the variable to a field symbols, you assign a new value to the field symbols, the same will reflect in the variable.

however, the variable should be active in memory else the ASSIGN to field symbols will fail

Hi,

Basically, the program needs to be executed to update a value.. so you can SUBMIT Program A from Program B.. Do an F1 on SUBMIT and there are a bunch of options with this statement..

I'm testing this and it is not working.

Program 1.



report zrich_0001 .

data: this_value(10) type c.

start-of-selection.

  submit zrich_0002 and return.

  write:/ this_value.

Program 2



report zrich_0002 .

field-symbols: <fs>.
data: field(30) type c.

start-of-selection.

  field = '(ZRICH_0001)this_value'.

  assign (field) to <fs>.

  <fs> = 'A Value'.

You may be able to do something like this. It is working for me.

Program 1



report zrich_0001 .

data: val(10) type c value '1234'.

start-of-selection.


  export val = val to memory id 'ZRICH_TEST'.

  submit zrich_0002 and return.

  import val = val from memory id 'ZRICH_TEST'.

  write:/ val.

Program 2




report zrich_0002 .

data: val(10) type c.

start-of-selection.

  import val = val from memory id 'ZRICH_TEST'.

  val = 'New Value'.

  export val = val to memory id 'ZRICH_TEST'.

Hai Martin

Defining a Field Symbol

FIELD-SYMBOLS <FS>.

Variable for later use

DATA FIELD VALUE 'X'.

Assigning a field to a Field Symbol

ASSIGN FIELD TO <FS>.

Using a Field Symbol which has an assigned field

WRITE <FS>.

DATA: EXTERNAL_RECORD(4000),

POSITION TYPE I,

LENGTH TYPE N.

FIELD-SYMBOLS <ENTRY>.

EXTERNAL_RECORD = '0005Smith0007Edwards0005Young'.

DO.

LENGTH = EXTERNAL_RECORD+POSITION(4).

IF LENGTH = 0.

EXIT.

ENDIF.

ADD 4 TO POSITION.

ASSIGN EXTERNAL_RECORD+POSITION(LENGTH) TO <ENTRY>.

WRITE <ENTRY>.

ADD LENGTH TO POSITION.

IF POSITION >= 4000.

EXIT.

ENDIF.

ENDDO.

Table work area for later use

TABLES CUSTOMERS.

Defining a Field Symbol

FIELD-SYMBOLS <OUTPUT>.

Displaying all fields of all table entries

SELECT * FROM CUSTOMERS.

NEW-LINE.

DO.

ASSIGN COMPONENT SY-INDEX OF STRUCTURE CUSTOMERS TO <OUTPUT>.

IF SY-SUBRC <> 0.

EXIT.

ENDIF.

WRITE <OUTPUT>.

ENDDO.

ENDSELECT.

Thanks & Regards
