Datamigration ATTR_ value

Hello everyone,

I want to update the supplier association number using a data migration job.
I have identified the relevant package to use: Supplier_Info_General_API.Modify__.

When I call this package through a PL/SQL script, it works as expected and successfully updates the value.

the package is called by the crud_update method :

supplier_handling_svc.crud_update(
                '*',
                v_supplier_id,
                'ASSOCIATION_NO' || chr(31) || v_association_no || chr(30),
                'DO',
                supplier_info_general## => ''
            );

However, when I run the same operation through the data migration job, no changes occur.

Any idea why please?

The select statement generated by the datamigration job do return the correct value :

Datamigration Job Details : 

The ATTR_ value used is : 

'ASSOCIATION_NO'|| chr(31)|| IC_I_SUPP_ASSOC_UPDATE_TAB.association_no|| chr(30)
