Delta package doesn't update data in 0FITX_O03

Hi,

Data updates made in custom characteristics "Ref key (head) 1" [XREF1_HD] and "Tax report date" [VATDATE] are not updated on BW side in 0FITX_O03.

Delta package works all right everyday.

The only way to update the data is to run full load.

Any help appreciated.

Regards, Leszek
