Credit Card Transactions
Credit card transactions are not supported by the Israeli Localization SuiteApp.
Consequently, there is no localized custom form for this transaction type, and the IL Tax Period field is neither supported nor updated at the transaction level.
The only reason credit card transactions appear in the Israeli VAT on Purchases report for the correct month is that the report relies on a native NetSuite field called Tax Period. This field is only visible in saved searches and reports and cannot be exposed at the transaction level, which is why the data reaches the report correctly.
The IL Tax Period field was originally created so users could view the tax period directly on the transaction record, since the native NetSuite field remains hidden.
Additionally, this transaction type does not flow into the Israeli VAT Summary Report and File Generator (the report used for official VAT filing). Therefore, even if the IL Tax Period field for Credit Card transactions was supported, it wouldn't resolve the issue, as the transaction would still be excluded from the filing report.
