Cannot enter negative value for number validation data type DFF segment when using ADFDi

Summary:

Hello Team,

Could you please help us with the following issue:

We can enter negative values for this problematic DFF segment on UI but not when using ADFDi.

Submission Option for Import Descriptive Flexfields is Yes without validation

We have a context sensitive DFF on a journal line level. 

There are

• Validation Type as Format Only
• Validation Data Type as Number

for this problematic segment.

We get the following error after Submit on ADFDi template:

The context and attribute values don't form a valid descriptive flexfield for Journals - Journal Entry Lines. (GL-780780)

We cannot find any solution on MOS.
