Summary :
When processing invoices via Transaction MIRO and referencing a purchase order with specific terms of payment that calculate the baseline date based on a fixed day with additional months, an error occurs. Using the amount split function leads to a duplication of the added months in the resulting FI document's payment baseline date. This discrepancy arises from a program flaw that fails to account for the terms of payment for subsequent split amounts. To resolve the issue, users should import the Support Package provided or apply manual corrections outlined, including the setup of new function modules such as FI_ZFBDT_DER_SET, FI_ZFBDT_GET, and FI_ZFBDT_MAN_SET via Transaction SE37.
