Datasource enhancements.

[Former Member]

Hi,

I had tried Datasource enhancement for Vnedor attributes datasource. When I saw the data in RSA3, I could see the fields populated but there is no data in them. I want the data to be populated. Can any one pls solve this issue. Also if any documentation(latest) on DS enhancements, Pls share with me.

Hi,

In RSA3 change the number of records displayed to more number and check it..may be there is no data for the records you selected.

I gave the maximum no of records...

That's not the problem..

Hi

Why you are using some code in SE38 and then calling it in exit, instead try to put all the code in CMOD exit only.

thanks and Regards

put a breakpoint after your select statement and check if any data is retrieved from the R/3 tables...

return with feedback, then will take on the next step

Did you write the code for enhanced object?

[Former Member]

Yes I had written the code in CMOD and SE38.

Hi,

Debug from RSA3 and trace this. Also, check the option selected for field in DS (Selection, Hide, Field only exit). Make this as selection if you need this selection for data load.

Hi,

There are 2 codings. One in TCODE CMOD and the other in TCODE SE38. There are no errors in these codes.

The code in Tcode CMOD:

DATA: L_PROG_NAME LIKE TRDIR_NAME.

CONCATENATE 'ZBWIN_' I_DATASOURCE INTO L_PROG_NAME.

PERFORM EXECUTE_USER_EXIT IN PROGRAM (L_PROG_NAME)

TABLES I_T_SELECT

I_T_FIELDS

C_T_DATA

C_T_MESSAGES

IF FOUND.

The code in SE38:

REPORT ZBWIN_0VEN_COMPC_ATTR. type-pools: sbiwa. constants : gc_vbeln type vbeln value '2'. *&----
