Can we do BDC Recording for Memasssa T-code

HI team, MY requirement is to update confirmation control key as blank (EKPO-BSTAE).

To update this value we are using mass transaction MEMASSSA in the custom program as null value can not be updated ME32l.

I have done BDC recording for MEMASSSA t-code, but when i am processing it null values is not getting updated. Manually i can able to do it using MEMASSSA.

Can we do BDC recording for Memasssa t code?
