Sequence Error in AP Batch Payment Form

Question

Hi all,
i've customized AP batch payment form via custom.pll enabling check_date in some cases. It works fine, but after updating the date i receive the following error message:
"APP-FND-01702:An assignment does not exist for these parameters and one is
mandatory"
Do you know how can i solve it?
Thanks,
Simona

Answer 1

all the metalink docs are suggesting its a setup problem:
1. In System Administrator Responsibility navigate to Application>Document>Categories
Using the Find torch ensure you have the Category defined that you require.
2. Create a Sequence
Navigate to Application>Document>Define
Name - whatever you wish to call it (must be unique)
Application - Oracle Payables
Effective From - Assign a date in the past - say 01-JAN-04 (your choice)
To - Blank
Type - Automatic (if you wish the sequence generator to assign a number)
Message - your choice - do you want a pop-up window to display the value when assigned?
Initial Value - your choice of starting value
SAVE
3. Assign the Sequence to the Category
Navigate to Application>Document>Assign
Document Tab
Application - Oracle Payables
Category - whatever you used in 1 above
Set of Books - your SOB value
Method - Manual
Assignment Tab
Start Date - when you want the sequence to start being assigned (cannot be before Effective From
Date from 2 above)
End Date - Blank
Sequence - Your sequence name from 2 above
SAVE
