I had copied the function module FI_OPT_ARCHIVE_CORRESPONDENCE to a custom function module and that is placed in the BTE and this function module has contains the correspondence types SAP01 (payment notificiation) and SAP08 (account statement) and i am planning to add new one i.e SAPP01 and what will be the Document type.
and SAP01 and SAP08 has the document type FIOPAYCONF,FIOACCSTAT
My question is could you please let me know where i can see the document type for the additional correspondence types so that i need to pass in that function module
