WD java -- Bapi - Export structure is blank

Question

Gurus,
We are calling R3 to save/change/create data. We do call BAPI_TRANSACTION_COMMIT after this and also they both are imported in the same model.
The following code executes successfully and bapi gets executed but data in the import structure does not get transfered:
projectNumber = wdContext.nodeZ_Gp_Save_008_Input().nodeGp_Detl_008().currentGp_Detl_008Element().getProj_Num();
wdContext.nodeZ_Gp_Save_008_Input().currentZ_Gp_Save_008_InputElement().modelObject().execute();
wdContext.nodeOutput_save().invalidate();
msgMgr.reportSuccess(projectNumber);
The data is in the child node [currentGp_Detl_008Element] equals to export structure in bapi is blank,
Just to recap bapi is been called successfully we are able to see a new record in R3 table but it is empty. It only has a timestamp and an identity they are both added by a bapi. but the data sent with the inner node [currentGp_Detl_008Element] through export does not make it to R3.
Help is very much appreciated,
Thanks
Shahid

Hi,
Did u write Two function modules or one?
If you are using the one function module Then that function module contains import and export params.
Here the input of the FNmodule is Import params and outof the Fn module u need to give any message after saving ur data in R/3 side for that sake u need to provide one value attribute from R/3 to WD side.
Do mapping and binding well and see the input will go correct or not.
Then it should work.
Or otherwise send me ur context structure and explain ur BAPI functionality such that we will see where is the problem.
