ID Server
Configure object IDs using constants and variables
Unique sequential IDs
Also see the ID Server chapter
IDs are flexible, making use of abbreviations for LIMS objects. They are configured on the Bika Setup ID Server tab

For Samples and their Samples, as well as Batches, Worksheets, Reference samples, Invoices etc.
- All IDs are unique and sequential
In standard configuration, Sample IDs (called Analysis Request here) are prefixed with the abbreviation for their Sample Types and year, e.g. Ore19-001 for the first Ore sample of 2019
Often seen in Geochemistry where ore and drill core samples are expensive but nonperishable, and in health care, where specimen are stored frozen, Samples can be retested, say for different analytes
To maintain a one-to-many relationship between Samples and and secondary analysis requests, the latter simply gets a sequential postfix their parent Sample IDs
Often set to S1, S2. e.g Ore19-001-S1 for the first Sample, and Ore19-001-S2 for a secondary, Ore19-001-S3 etc.
Restest and Sample Partions get their IDs in similar fashion, based on the parent Sample ID
