Hi,
In the portal side, you will see # value shown for charcteristic in the following cases:
When the Key for this Characteristic value is maintained as blank i.e. # in the Info Object Settings in the transaction RSD1 in the relevant BW Backend system.
and when no text value is maintained for this characteristic value i.e. <blank>in the Info Object Settings in the transaction RSD1 in the relevant BW Backend system.
This is because for every characteristic value, it has a Key and Text value associated with it and when Text value is blank, Key value is checked and if this Key Value is #, # is seen in the portal side.
In Java Web side, # will be seen if Text value is not maintained.
Thanks & Regards,
Sapna
