Access deep structures using string

Former Member — Thu, 27 Sep 2012 09:20:20 GMT

Dear All,

I have to develop dynamic mapping between two different structures (not a BOL objects, just structures so bPath doesn't work here).

I know exactly how both structures look like - got the info in two strings.

Let's say I have these two strings:

1) 'struct1-childStruct1-childStruct2-someField1'

2) 'struct2-childStruct3-someField2'

let's saym I'm sure the types inside are the same, so there will be no conflicts. What I need to do is following:

struct1-childStruct1-childStruct2-someField1 = struct2-childStruct3-someField2.

Seems to be easy, but I have only string representation of both structures. How can I achieve it?

Thanks in advance!

Hello Pawel,

have you tried to use field symbols:


 types: begin of t_struc1,
  field1 type c,
  field2 type numc04.
types: end of t_struc1.

types: begin of t_struc2,
  field1 type c,
  field2 type numc04,
  struc1 type t_struc1.
types: end of t_struc2.


field-symbols:
  <src>   type any,
  <dest>  type any.

data:
  ls_struc1  type t_struc1,
  ls_struc2  type t_struc2,
  l_string1  type string value 'ls_struc1-field2',
  l_string2  type string value 'ls_struc2-struc1-field2'.

ls_struc1-field2 = '0014'.
ls_struc2-struc1-field2 = '0027'.

assign:
  (l_string1) to <src>,
  (l_string2) to <dest>.
assert <src> is assigned and <dest> is assigned.

<dest> = <src>.

Kind regards,

Hendrik

Hi Hendrik,

I've tried your suggestion. In debugger all fine, no errors, but at the end new value is not present in the structure..

Ok, you were right. I've written

assign l_string1 to <src>

instead of:

assign (l_string1) to <src>

thanks a lot!
