why system creates GUID?

[Former Member]

Hello Gurus,

I am new SRM. I see GUID is being created for the objects (SC, PO, Vendor etc) in SRM system. Why do we need this? For ex: for Shopping Cart, SC number is the unique identifier, then why do we need GUID for SC?

Thanks,

Hi Chandra,

GUIDs are system generated unique keys which identifies CRM and SRM objects (Shopping Carts, Invoices, business partners, products , category ID etc.). SRM & CRM & MSA works on GUIDs. Most of the table relationships are defined on GUIDs.

Guid – Globally Unique Identifier

Used as primary keys in SRM tables.

All transactions are uniquely identified by their guids internally

Transaction numbers are not unique

<b>Another reasoning:</b>

GUIDs (Globally Unique Identifiers) serve as primary keys for all tables in the CRM. A GUID is generated by a special algorithm using as input data certain hardware information of the host computer, the current system time, and a randomly generated number. The GUID can be represented in two formats: a 32-byte character field or a 16-byte raw sequence. It is globally unique in the sense that two GUIDs produced on any two computers (or even on the same one) at any time can never be the same.

Pls assign points if answer is usefull !
