NoticeAccording to the DeRE Guidance Manual (Chapter III, item 2.1.2), the deadline for submitting monthly periodic events is set for the 15th of the following month., It will not be extended if it falls on a Saturday, Sunday, or public holiday..
Guidelines for broadcasting events
In accordance with the guidelines established in the DeRE technical documentation, the Taxpayer Table Events must be transmitted prior to the delivery of the corresponding Monthly Periodic Events, in order to ensure that the registration and structuring information is properly received and validated before the processing of periodic events.
Additionally, it is recommended that Events that have a logical dependency relationship should not be transmitted in the same batch., especially when the validation of an event depends on information produced or altered by another event that has not yet been successfully processed.
For example, in the event of simultaneous transmission of an update to D-1011 – Annotated General Chart of Accounts (PGCC) and of the D-1101 – Monthly Balance Sheet, The eventual rejection of D-1011 will not necessarily prevent the processing of D-1101. In this situation, the trial balance validations may be performed based on the PGCC version previously in effect in the DeRE database.
In order to ensure the consistency of the information provided, it is recommended that the following operational sequence be observed:
- Transmit the Taxpayer Table Events (D-1001 and D-1011);
- Please wait and verify that the processing has been successful;
- Correct any inconsistencies identified by the system;
- Only after confirmation of receipt and validation of these events will the Monthly Periodic Events be transmitted.
Following these guidelines will contribute to the proper execution of DeRE validations, reducing the occurrence of rejections and processing based on information previously existing in the database.
