JE_Batch_id and JE_Header_id sequence Values

Hi All

We need to clarify how the sequence of je_batch_id column of gl_je_batches tables and je_header_id column of gl_je_headers table in Cloud are getting generated.

We observe the ids are jumping from the sequence and since we need to capture the actual Batch and journal Ids in a target system for references, we need to understand the criteria on which these Ids being generated automatically, and can these be user defined?

Thanks in advance..
