how to call a function with generic table parameter

Hi everybody

I need to call function module RSAR_ODS_API_GET (from BW). It recive an internal table with request ids and should return in E_T_DATA "unstructured" data from the psa and in E_T_RSFIELDTXT the description of the data structure, I guess

from sap help only thing I have reggarding how to use the function module is :

"You can call up the function module RSAR_ODS_API_GET with the list of request IDs given by the function module RSSM_API_REQUEST_GET. The function module RSAR_ODS_API_GET no longer recognizes InfoSources on the interface, rather it recognizes the request IDs instead. With the parameter I_T_SELECTIONS, you can restrict reading data records in the PSA table with reference to the fields of the transfer structure. In your program, the selections are filled and transferred to the parameter I_T_SELECTIONS.

The import parameter causes the function module to output the data records in the parameter E_T_DATA. Data output is unstructured, since the function module RSAR_ODS_API_GET works generically, and therefore does not recognize the specific structure of the PSA. You can find information on the field in the PSA table using the parameter E_T_RSFIELDTXT."

unfortunately I when running de report bellow, I get a dump which says:

Function parameter "E_DATA" is unknown

in the definition of the interface E_DATA has no type, which means it can recive any table type, right?

So I have two questions?

1) How to get the code working

2) How do I use the parameter E_T_RSFIELDTXT to parse the data returned in E_DATA

by debuging RSSM_API_REQUEST_GET for this code I found it try to put an internal table with the struct of the database table /BIC/B0000151000 in E_DATA

Thanks a lot for any help

Try to pass table parameter without "[]" :


CALL FUNCTION 'RSAR_ODS_API_GET'
EXPORTING
I_T_REQUEST = lit_request1
IMPORTING
E_ODSNAME = lc_dtarget_name
E_T_RSFIELDTXT = lit_meta_data
TABLES
E_DATA = lt_psa_data

Thanks for the advice Peluka, but I think the function parametr should have de brackets because of the header line, anyway It doesn't work either as you suggested

thanks

The parameter is E_T_DATA not E_DATA
