Go to transaction OMET
Click on “New Entries”.
Enter the following values as shown below:
Function authorisation: restrict qty of PO to PR
Field selection: me21
click on adopt PO price
Save your entries.
Now we need to assign this function to the corresponding end users. Go to Transaction SU01 OR SU52 -> Click on tab “Parameters”. Maintain the parameter EFB.
Now we need to set an error message when the end user tries to create a PO greater than PR.
Click on System messages.
Click on “New Entries” and create the following entry.
Save and Exit. Now whenever the end user tries to create a PO with quantity in excess of that in PR, then the above error message would appear. If you just want a warning message to be shown, change the message category to ‘W’.
