RFC Adaptive model in web dynpro application gives mandatory parameter erro

[Former Member]

Hi,

I need to check when we create model to call bapi from backend, are there any checks for the input data which are done by the model before the bapi is called ?

I am passing some input parameters and I get the following error on the screen. and the return structure is empty.

Mandatory parameter BFLUSHDATAGEN of method BAPI_REPMANCONF_CREATE_MTS missing

But if I pass the very same paramters directly in se37 transaction to the bapi, then this error is not seen. it gives some other error in return structure.

There fore I have a doubt is there any check which doesnt call the bapi at all if it doesnt find the parameters it is looking for. I know the paremeters are not correct but I expect to see the same error what is seen in se37 in the return structure of my modal context element.

thanks in advance for help.

Hi,

I am not sure if that is possible. You need to precheck with your own code only if the input parameters are filled (b4 executing the model). Once executed, whatever error is returned by BAPI to Webdynpro container is displayed on the screen. It would be mostly the same error that comes in backend.

Hi,

Can you post both errors ?

Is it some thing to do with the language?

Hello,

I have posted the whole error. it is not a stack.

It is just like the error message seen when we leave a mandatory parameter empty.

This would mean that I am not populating the modal node elements properly

But in the code, just before the bapi is called ie before the statement

wdContext.currentBapi_Repmanconf_Create_Mts_InputElement().modelObject().execute();

I have put a message statement to display the contents of the modal node ie structure BFLUSHDATAGEN. and I can see data there.

But still it behaves as if I have left that empty.

kindly help

thanks

Hi Rita,

Does it work if you set some value to this parameter - BFLUSHDATAGEN by your own?

hi,

yes I did

wdContext.currentBflushdatagenElement().setMaterialnr("100-400");

even then it says the same error

[Former Member]

Is there any other parameter inside 'Bflushdatagen' apart from 'Materialnr' which you might be missing to set?

HI,

Pass parameter for both BFLUSHFLAGS and BFLUSHDATAGEN.

in se37 the structure is mandatory

but i assumed that doesnt mean that i have to pass each and every field of that structure

so passing one field should be enough for a mandatory structure to give value

I dont agree with that. If you look in to the source of this bapi you will see calls based on other parameters from BFLUSHDATAGEN-MATERIALNR_VERSION

BFLUSHDATAGEN-MATERIALNR_GUID

Try to consult with some one who knows abap to suggest you related with the mandatory params.

hi, I have corrected my code and written the below code inthe controllers init method.

Bapi_Repmanconf_Create_Mts_Input parent = new Bapi_Repmanconf_Create_Mts_Input();

wdContext.nodeBapi_Repmanconf_Create_Mts_Input().bind(parent);

Bapi_Rm_Datgen input1 = new Bapi_Rm_Datgen();

wdContext.nodeBflushdatagen().bind(input1);

input1.setMaterialnr("100-400");

input1.setPdc_Number("100066");

parent.setBflushdatagen(input1);

Even this I getmandatory paramter missing eror

kindly help
