Reproducing the Issue
- Go to the Business Configuration work center.
- Select the Implementation Projects view.
- Select the project line.
- Click the Open Activity List button.
- Search for the activity Accounts/Suppliers.
- Select the activity.
- Click the Open button.
- Click the Maintain Payment Terms hyperlink.
- Click the Add Row button.
- Enter value for Number of Days After Invoice Date / Receipt Date.
- Check the checkbox under Specification of time duration.
- You can maintain Fixed Day of Month and Additional Month, however, Number of Days After Invoice Date / Receipt Date changes the value to zero and it becomes grayed out.
You cannot combine 'Number of Days After Invoice Date / Receipt Date' and 'Fixed Day of Month' in one customized payment term.
Default payment terms(those that does not start with Z) like for example "45 days from Invoice Date, End of month" and "End of Month of Invoice Date, 45 days" are different as they were designed and delivered by SAP based on business rules ,so you cannot create new payment terms similar to them as thease are standard payment terms.
Currently this is a new requirement for us please vote and comment of existing request in customer influence forum.
There are only two options for you on the custom Payment Terms:
a) If you check the option ‘Specification of time duration’:
You can set the fields: Discount Rate + Fixed Day of Month + Additional Month
b) If you do not check the option ‘Specification of time duration’:
You can combine: Discount Rate + Number of Days After Invoice Date / Receipt Date
