Setting up maximum order value for vendor

Question

Hi experts,
I want to set a maximum price/value limit for vendor for giving order
For example - i want to set a maximum limit of 1lakh for vendor A
when ever I create PO for vendor A , system should chck the maximum value for A vendor.
And if there a many open order for vendor A, then the total of open PO's shoukld be
counted and when ever i am creating new PO & if ec=xceeds the value 1 lakh then
system should not allow to create the new PO
Vendor A       PO1     value - 50000      status - open
vendor A     PO2     value - 30000     status - open
vendor A     PO3     value - 40000     status - creating now
At the time of creating PO3, PO value exceeds the vendor limit, so it should not allow to create/save the PO3
please let me know how to handle this

Hi,
This can get really complex unless you have clear vision of what you want to control.
For example, the maximum limit that you want to set, is it for the current month / current year etc?
If it is the sum of all Open PO value, would you consider the PO's that were created the sme month and delivered but payment is pending though Invopice is posted?
So answers to such questions provide the clarity for teh controls that need to set in place.
For this you can create a Z table and maintain the limits that you like to set based on the criterion like monthly or yearly.
Then Use a user-exit in the PO to calculate the net value of all open PO's for the vendor and then validate with the Z table and throw an error if it exceeds.
However the performance may get effected with such calculations on PO save.
in that case you may have to consider storing the cumulated PO value on every PO creation and PO Completion.
Consider all this and take a decision.
hope this helps.
