How make validations before saving a Purchase Order ?

[former_member425121]

Hello

I try to make some validations to header data captured when creating/changing Purchase Orders (ME21N/ME22N), especially to Vendor Field.

Does somebody knows a User Exit wich allows me to do this ?

I need to release the development just tomorrow, so please help me !!

Thanks in advace.

Thanks Venkat

I tried this enhancement, i made some tests and it is just what i need !!!

I tried with User Exit _012 but this doesn´t has the table with Partners Functions (wich i need to validate too), but User exit _013 has tables XEKPA/YEKPA with these Partner Functions, so it's just wath i was looking.

Thanks a lot !!
