Issue in Updating Customer specific fields in WBS using BAPI_BUS2054_CREATE_MULTI

Question

Hi Experts,
I am able to create the WBS element using BAPI_BUS2054_CREATE_MULTI.But the issue is i am not able to update customer specific fields even after passing the fields as per specification in Function module documentation. I have also created an implementation of BADI  as per below specification in FM documentation:
Procedure for Filling Standard Enhancements
Before you call the BAPI for each object that is to be created or changed,
for which you want to enter customer-specific table enhancement fields, add a
data record to the container ExtensionIn:
STRUCTURE:    Name of the corresponding help structure
VALUEPART1:   Key of the object + start of the data part
VALUEPART2-4: If required, the continuation of the data part
VALUPART1 to VALUPART4 are therefore filled consecutively, first with the
keys that identify the table rows and then with the values of the
customer-specific fields. By structuring the container in this way, it is
possible to transfer its content with one MOVE command to the structure of the
BAPI table extension.
Note that when objects are changed, all fields of the enhancements are
overwritten (as opposed to the standard fields, where only those fields for
which the respective update indicator is set are changed). Therefore, even if
you only want to change one field, all the fields that you transfer in
ExtensionIn must be filled.
Checks and Further Processing
Using the methods ...CREATE_EXIT1 or. ...CHANGE_EXIT1 of the BAdI
BAPIEXT_BUS2001, BAPIEXT_BUS2002, and BAPIEXT_BUS2054, you can check the entered
values (and/or carry out other checks).
In the BAdI's second method, you can program that the data transferred to the
BAPI is processed further (if you only want to transfer the fields of the CI
includes, no more action is required here).
But still i am unable to update fields though i am able to create WBS with rest of the fields except  custom fields.
I am using attached code to achieve this.Do we need to code anything inside method create_exit1 or create_exit2 implementation for BADI or
Please help on priority

Hi Rahul,
First observation from your code is that i could not find the assignment for the field
GWA_WBS_EXTIN-STRUCTURE. I hope you are not filling this field, that could be one reason for failure. Try to do it and let us know if you still have the problem.
