Hi Willie,
Thanks for your reply. Yes, you are correct. I have checked payment card types and Rules in ECC & CRM system but everything is correct. Mentioned function module is not available when check in SE37 (crm system). I was downloaded payment card type and rules (TCC1 & TVCIN) from ECC to CRM.
I was refereed below note also but not resolved. is there any cause for this issue?

Thank you Regards Vijay
