Blanket Purchasing Documents

Hi all,

I have a scenario on which i need help.

I create a Blanket PR with certain limits say $10000 and wanted to create multiple Blanket PO with reference to this Blanket PR.

The system should NOT allow me to exceed the limit mentioned in the Blanket PR.

For E.g.,

1st PO limit is $5000

2nd PO limit is $3000

If 3rd PO limit goes above $2000, the system should throw an error message.

How to configure this scenario?

Regards

B.Vijay
