Organisation Code on Organisation Parameters Form

Hi,

I am trying to complete the Inventory Parameters tab in the Organisation Parameters form but not sure what value to enter in the Organisation Code.  Is this value systems generated, that is do I need to find it somewhere in the system or can I simply give it any value?

I am hoping that this will resolve an issue I am having in completing the Financials Option in Payables whereby an error message "FRM 40212 - Invalid value for field DSP_ORGANISATION_CODE" when I try to enter the inventory organisation on the Supplier - Purchasing tab.

Thanks

Winnie
