Prepayment Purchase Order GST/VAT

Hi,

To help with the below we use:

- LS Central

Recently, I've started encountering issues with any prepayment vendors that are configured either at the Vendor level or the document level. The G/L has default settings against it such as this:

I've been told that if the posting setup is like the above where GST0 is declared, that only GST0 entries can be posted against the G/L. Outside of Prepayment I have confirmed that this isn't the case. However on any prepayment documents this will error highlighting that the GST combination does not match the G/L.

Is standard d365 behaviour to have multiple G/Ls for prepayments to handle different GST/VAT combinations? That seems like an anti pattern.

Thanks!

Hi Jacob,

Thanks for your question. You're right to question the behavior you're seeing—handling GST/VAT combinations in prepayment purchase orders can be tricky in Dynamics 365 Business Central, especially when default posting setups are involved.

Here are a few insights:

Standard Behavior
- In standard D365, prepayment posting is more restrictive because it uses prepayment accounts that are tightly linked to specific GST/VAT posting groups.
- This is why you're seeing errors when the GST combination doesn’t match the G/L setup.
Workaround Options
- One approach is to create separate G/L accounts for different GST/VAT combinations used in prepayments. While it may seem like an anti-pattern, it’s a common workaround to avoid posting errors.
- Alternatively, consider using intermediate clearing accounts or adjusting the GST posting setup dynamically via customization.
Consistency Outside Prepayments
- As you've noted, regular purchase orders allow more flexibility. This inconsistency is due to how prepayment logic enforces stricter validation to ensure tax compliance.
Recommendation
- If managing multiple G/Ls becomes too complex, you might explore customizing the posting logic or using Power Automate to route prepayment entries based on GST group dynamically.
