Too long form name: PBAFrontEndWebApprove_PBN

This error happens in AX 2009 product builder due to incorrectly set up number sequence. To fix it:

1. Go to Product builder > Setup > Parameters

2. To to tab Number sequences

3. Highlight record where Reference field = Product model number 

4. Right-click in the Number sequence code field

5. Click Go to Main Table Form. That brings you to the Number sequences - the form that lists all AX counters and numbers, their formats, used in various areas of the application.

6. Set field Largest to 99999

7. Set field Format to PBN_#####. That will make sure that when PB needs to generate a form, the Object name will fit into the length of the object. Alternatively, you can shorten or cut off the PBN_ prefix to allow for more than 99999 product models.

8. 

9. Now for NEW product models you'll be able to generate web-forms. If you have already created long product numbers, you can copy them to new, shorter ones, by creating a new product model with a shorter ID and using Functions > Copy from product model. 

Enjoy!
