To be clear about your inquiry, Do you mean that these PMAPY batches are posting in the originating module without updating the posting accounts in GL?
If this is the case, then it is related to the posting setup in which you choose whether to "Post To" or "Post Through" GL.
I don't suspect that different exchange rate would stop the batches from posting, exchange rate variances are usually handled when Multicurrency revaluation is performed.
Please provide us with any further details if any.
Best Regards,
