3405435 - Item in Project Invoice Request Does Not Have Option To Credit

In newly created Project Invoice Request the user is unable to change the option from Debit to Credit in specific item. 

SAP Business ByDesign

1. Go to the Customer Invoicing work center.
2. Go to Project Invoicing view.
3. Go to Sales Orders sub view. 
4. Search for ID ABC (ABC is the Sales Order's ID). 
5. Click in New button and select 'Automatic Project Invoice Request'. 
6. Navigate to Items tab.
7. Navigate to Invoice Items subtab. 
8. In the Proposed According to Sales Order Items section, we can see that there is a column 'Debit/Credit'. 
9. The value Debit is grayed out. 

So the user is unable to change the value from Debit to Credit. 

There are two cases:

Invoicing Method is 'Fixed Price': the field 'Debit/Credit' is editable while the Project Invoice Request has 'In Preparation' status. 

Invoicing Method is 'Time and Material': the field is not editable. 

The system is working as expected.
