How to call Sales Quote Web Service with Extended Fields from KUT

Hi Experts,

I am facing a problem updating a Customer Quote from WS. (Provided by Service Explorer and created in PID).

I have a extended Field from KUT.

With this values.

The problem is invoking a web service to change this values in the SalesQuote. (WS from Service Explorer)

I tried to change the value

Now a need this field with the value 106 ("Perdida").

This is the call from Soap UI Tool. (With the service obtained from Service explorer)

We see that the operation was succefull, but the value is the same. (not was reflected the operation in the Customer quote)

We tried to testing by creating a new WS from PDI. But i cannot see the values extended from KUT. (Only see the extended fields created in PDI)

Thx!!!
