Error while creating a Regular Price Change in RPM

Hi All,

I want to create a Regular Price Change in RPM. After selecting the Price Guide, the Reason Code, the Effective Date, the Change Type, the Location, the Department, the Item and press the Apply button, the following error is shown:

" Item Locations: The item 123456 does not exist at location 123 "

Checking in RMS - Item/Inventory location, the item exist at location 123.

Could you tell me how to fix this?

Thank you for your answers,

Adriana
