Hello,

Take a look at Sage North America Knowledgebase ID 3857.

I have copied and pasted the article here as reference.

Error: "Entry batch is full" in Payment Receipt entry.

Increase the Screen Dimension for the Payment Receipt Entry.

Note: The steps below utilizes the Sage X3 development tools to modify the system. Development training covers customization and should be taken to be familiar with the set of pre-defined rules needed for such customizations.

The Dictionary validation, steps 10 through 14, can take sometime to complete.

1. Have everyone exit from Sage X3.
2. Open Development, Data and parameters, Development setup, Activity codes (GESACV).
3. For Activity code, select PAY Number of Payment Lines.
4. Increase the value in the Screen dimension (version 6), Screen size (version 7 and higher) field by 100 or 200.
5. Click Save.
6. The following message will appear:
    Activity code modification must be followed by a dictionary validation.
    It is better to perform this change in the folder record and to revalidate the folder.
    Do you want to proceed with the change?
    Yes   No
7. Click Yes to continue with the changes.
8. Repeat steps 3 through 7 for Activity code PYL No. of Payments/Entry Batch.
9. Click Close page to exit the Activity code function.
10. Open Development, Utilities, Dictionary, Validations, Dictionary (VALDICO).
11. Check the Screen validation and Generated Windows check boxes.
12. For Activity code enter PAY.
13. Click OK.
14. Repeat steps 10 through 13 for Activity code PYL.
15. Log out of X3 and log back in.
16. Check the screen PAY4 in Development, Processing dictionary, Screens, Screens and make sure the line column on the general tab is blank. If not double click on it and validate the screen.
17. Additionally validate all the payment entry transactions that have the entry batch check box checked in Setup, A/P- A/R accounting, Payment entry transactions, input tab
