Hi

We are getting the below error when trying to creating a record in a custom form. This error atleast was not occuring until 3 days back.

APP-FND-01206: This Record Already Exists. You Entered a Duplicate Value Or Sequence of Values That Must Be Unique for Every Record.

Tables and Forms Design

------------------------------------

4 tables --> a,b,c,d

a has a primary key and is the Header tab of the form (Header which is a single record )

b has a foreign key to a and is Lines  tab of form (Lines tab --> Multi lines in a block tab)

c has a foreign key to a and is "Packing" tab of form (Packing tab- has a master c and detail d)

d is a child of c and is in the 3rd tab.

When we are creating a record , the above error is coming. Not sure what has changed.

Can you please provide right pointers to fix this issue ASAP
