PB in RFC function declaring table as CHANGING

frederic_r — Fri, 14 Jan 2011 08:01:58 GMT

Hi all,

I wrote an RFC function to get data between 2 SAP systems. I've to transmit to this function select-options felds. Therefor I've created a changing parameter in the function I_LFDAT type RSPARAMS_TT which is a table type with structure RSPARAMS.

I did it by this way as 'Tables are obsolete' in RFC functions.

My problem is that by calling the function I've a dump saying ' (ungültiger Datentyp 17)'. This means the parameter is not correct.

I checked anything and the table I'm sending has the same structure as the receiving parameter

thanks in advance for your help

Hi,

Are you changing the select-option table ? or else use it in the table parameter.

Is I_LFDAT is select option of date then use this RANGE_DATE structure .

No I'm not changing the select option table but I've another table in wich I write some records and send them back to the calling system.

I put all the tables in the TABLE tab instead of the CHANGING tab and it works... but by saving the FM I've the message 'TABLES are obsolete'...

Hello Fred

I am not really a fan of CHANGING parameters in fm's.

Since you have the table type RSPARAMS_TT I would recommend to use the following approach:



DATA:
  lt_seloptions   TYPE rsparams_tt.  " itab with select-options

" fm signature with 2 parameters:
...
  IMPORTING
    it_selopts = lt_seloptions
...
  EXPORTING
   et_selopts = lt_seloptions
...

The RFC-fm gets IT_SELOPTS as input, can change them, and returns them as EXPORTING parameter ET_SELOPTS.
