SD_CUSTOMER_MAINTAIN_ALL creates customer but can't find in SAP

Hello experts,

I'm trying to use BAPI 'SD_CUSTOMER_MAINTAIN_ALL' to create customer. I've filled it's I_KNA1, I_KNB1 and I_KNVV structures. In the Export Parameters

I've values in E_KUNNR = 1064,

O_KNA1 = Full with details (Refer to screen shot)

E_SD_CUST_1321_DONE = X.

Does this means my customer has been created (1064) ? When I search it in KNA1 I don't see it neither through XD03. Please suggest.

Many thanks in advance.
