6.2 Batch constraints

The maximum size of a batch is not defined in this part of the ECM standard but shall be in accordance with the bilateral agreement between the sender and the recipient of the messages.

Data about the same Entity Cluster shall only be contained in one message of each batch and shall only be contained in one batch of each set of batches if the sender chooses to submit data in several batches.

The maximum time a batch may be kept “open” is determined in accordance with the bilateral agreement between the sender and the recipient of the messages.

To ensure sequential processing, a batch is identified by the date and time of its creation in the form YYYYMMDDhhmmssuuunnn (BatchId) with:

  • YYYY being the year of batch creation;

  • MM being the month of batch creation;

  • DD being the day of batch creation;

  • hh being the hour of batch creation;

  • mm being the minute of batch creation;

  • ss being the second of batch creation;

  • uuu being the millisecond of batch creation; and

  • nnn being the nanosecond of batch creation.

 

The message sender shall ensure that the BatchId is unique for each of the message recipients with which it communicates ECM messages.
