Migration of telephone extensions in business partner master data (customers / vendors)

[bg21071968]

In the staging approcach for migration of business partners (xml file for customers or vendors) there is the possibility to migrate 3 telephone numbers, fax numbers and mobile phone numbers.

But the telephone numbers and fax numbers in the fiori apps and the gui are separated in the main number and the extensions. In the meanwhile, the extensions are not supported by the migration cockpit.

Does anyone has already adapted this?

Recently this was a requirement for my project if you had adapted this plz share the information..Telephone default , Telephone 1 & 2 are available in General & Addresss sections , Extensions are not available, had created custom field for extension ZZ_TELEXTENS1,2 & 3 but could map only to available field of extension in target under RR_Communication Data , So when load executed the 1st telephone extnesion values is created for all the extension fields. Any idea how to over the this issue.
