Data Model Upgrade Fails with ORA 01422

Hi all,

I'm trying to upgrade the Data Model by doing the following modifications:

Time bucket - Week -> Day
Source type - Oracle tables -> Text files

And I mapped the informations as follows:

Item code - Item(t_ep_item)
Item description - dm_item_desc
Item Subclass Code - e1_item_cat_1
Item Subclass Desc - e1_i_cat_desc_1
Item Class Code - e1_item_cat_2
Item Class Desc - e1_i_cat_desc_2
Item Series Code - e1_item_cat_3
Item Series Desc - e1_i_cat_desc_3

Store Code - organization (t_ep_organization)
