Hi Priti,
In this case, Table Creation in ECC and RFC creation would be same.
- Now when a user selects Country and Sales Org, he/she should save the request after entering all the related information. You might be having some kind of "Status" field, you can update this field with some DUMMY status to show that Tax information is not added yet.
- Create 1 Syndication Port, which will syndicate(auto-syndication) new Created records with this DUMMY status.
- Now, PI system will pick this file and execute RFC for populating Taxes values and populate these details in XML file(XSD will be generated by PI team and that needs to be uploaded in the Repository) and send it back to MDM inbound folder.
- This file can be auto-imported using Import maps to update Tax Classification and Category Codes for given Material.
- Also you can update the status to "Approved" or something so that this record is then auto-syndicated to ECC system.
This will solve your purspose of auto-populating Tax values for given material.
Please let me know if your have any doubts/concerns for the same.
Thanks and Regards,
Ankush
