How to find user exit for for "On save" of MIR4?

[walkerist]

I'm trying to map the UUID into CFDI.

My process is MIR4>Input UUID field>then save. After saving the UUID must be mapped in CFDI. 

What user exit should i edit for this?

Hello @walkerist 

As per Logistics Invoice Verification BAdI documentation

you can use INVOICE_UPDATE BAdI.
