ADRC Table

Hi ,

I created a customer from XD01 and also filled the street field in same transaction but i did not fill street2 and street3 fields. I want to update street2 and street3 fields from an abap program.

I am trying to fill the customer's street2 and street3 field in ADRC table.

But sy-subrc = 4. It is failing.

UPDATE adrc SET str_suppl1 = 'street1'

str_suppl2 = 'street2'

WHERE addrnumber = 63534.

can someone tell y subrc is 4? why it is not getting updated?

Thank u
