CVI between BP and Customer (In ECC 6 SP5)

[itzikd]

Hi,
I have a requirement to integrate custom ZZ-fields between Customer and BP (and BP to Customer).
I have Z field in customer which need to be update to standard field in BP and vice versa the same field need to be update from BP to Customer.

Be attention we are working on ECC 6 SP 5 (which mean old version).
I already read the blog  https://blogs.sap.com/2019/11/07/sap-s-4hana-business-partner-field-enhancement/
but it is not suitable to my system.
The CVI_CUSTOM_MAPPER already created.
Any suggestion how to solve this requirement?

Best Regards,
Itzik

CVI_CUSTOM_MAPPER allows multiple implementations, what is your exact problem?

Hi,
Thanks for for your reply.
The link below is solution for S/4 Hana while we are using the ECC 6 version,
so this solution is not suitable for me. 😁
About my requirements
Need to sync Z field from Customer to BP (standard field  SMTP)
and vice versa (From BP field SMTP to customer Z field).

I extend the structure CMDS_EI_EXTERN with my Z field.
In customer. I change the Z field with new value and save.
In method MAP_CUSTOMER_TO_BP the Z field is empty without any value.
my question is how we get the new value in method  MAP_CUSTOMER_TO_BP?

From BP side, I change the SMTP field and save, 
in method MAP_BP_TO_CUSTOMER the field SMTP has value.
How I pass this value to the Z field in KNA1?
I place the value in the Z field, but the value does not saved in KNA1.

please let me know if you need more info.

Thanks in advance,

Itzik
