Validate mandatory field TAXNUMXL when creating or modifying business partner

Hello everyone, the idea of ​​this post so you can validate that the tax number is not empty when creating or modifying a business partner.
My name is César Orsi, I am SAP FICO Freelance consultant with more than 12 years of experience. I am from Argentina. My current position is SME, I am leading a S4 HANA project with Central Finance.
I hope to participate actively in this wonderful forum and contribute my grain of sand. I hope you like the post and help them!


To validate that the TAXNUMXL field is completed when creating or modifying a BP, it must be configured in the following path: Cross-Application Components --> SAP Business Partner --> Business Partner --> Basic Settings --> Field Groupings --> Configure Field Attributes per BP Role:

Select "Configure Field Attributes for Each Role Category"

We must select the Role in which we want to validate the field, for example select "FLVN00":

Press "Field Grouping", then select the data set "Tax Number" and double-click. On the right, mark "Req.entry":

 

We save and do a test, when trying to create a BP we will ask that the TAXNUMXL field be completed:

I hope you serve them!

Greetings and thanks!
