MIGO & MIRO no fx difference posting

Question

Hi,
we had requirement i.e when we create po based the date system will pickup exchange rate say 0.658 and when we create migo that time rate was 0.789 and when we do miro rate was 0.8941 in GRN and MIRO entries getting posting when we do miro system posing the diff amount in price diff a/c now business they don't want to post any price diff entry.
I had check in the PO there is check box fixed rate if we tick the same exchange rate get flows up to miro and it's working fine.
now my question is how we can keep that check box default for some vendors is there any filed exit / user exit/ screen exit  / any body needs to impliment or any substituion we can go about it.
any one have done same scenario???
Regards,

Answer 1

As per your requirement you want to set the field tick for some vendor.
If you do this at document type level, then it will be applicable for all vendors (Also you can't set the tick mandatory with field selection).
If you do this via Transaction variant, then you can restrict this for different user (but not for some vendor).
You have the last option as development (using badi or user exit)
I suggest, sit with your abap team and create a Z table for the list of the vendor which has the exchange rate tick is mandatory (using Z table, you can change/remove or add any vendor anytime from functional side)
Then write the logic as per your requirement on an user exit or badi.
Here is a document to find available user exit or badi for a transaction
