Blanket Purchase Order sub-limits

[Former Member]

Hi Experts,

I'm trying to create yearly blanket Purchase orders for some periodic invoices the company is expecting each month.

They don't want that all the Overall limit amount could be used in one invoice in the first month.

In the help for the Overall Limit field, it says in Dependencies, If you have also fixed sub-limits within the overall limit for an item, each time services are entered or goods receipts are recorded the system checks whether the individual sub-limits and the overall limit have/has been adhered to.

How can I define the sub-limits?

Is there a configuration point to allow entering the sub-limits?

Thanks in advance
