need the IO to map AUFSD field in 0CUST_SALES_ATTR in BW

Hello

I have requirement where we are need the Customer order block information in BW for 0CUST_SALES and the corresponding field is AUFSD which is hidden and I have unchecked it in 0CUST_SALES_ATTR data source in ECC so that I can pull the data in BW.

I have checked all the tables like RSOSFIELDMAP which gives the mapping Infoboject information. But I do not see any standard info object in BW to be mapped for this field AUFSD.

Can anyone please confirm if there is a standard IO for this field? or I should create a custom one?

Thank you
