Change binding of Standard SAP Field

Hi All - I need to change the binding of a Standard SAP field in WD.

I have a Standard Field bind to a Standard SAP Structure but the Binding does not have the correct field that my client required. The correct field is another field in the same structure.

I already populate the correct value in the structure using the correct BAdIs but I want to bind that Standard Field with the field that has the correct value. (also a standard field)

I go to enhancement framework and I don't have the S_DEVELOP Authorization (meaning I'm not SAP)

How I can change the binding or how I can overwrite the value of that field?

thanks!
