Summary:

Facing issues in the extract as | symbol is restricted in extracts

Content (please ensure you mask any confidential information):

We have configured extracts in planning modules to a downstream system with | as delimiter. With the latest upgrade, i couldnt make changes to the extracts as I m getting "The delimiter parameter cannot start with or contain a delimiter followed by restricted characters including Equals (=), Plus (+), Minus (-), At symbol (@), or Pipe (|)". We have implemented them in the production systems. Changing the delimiter now will have significant changes in the downstream systems. is there a way where we are allowed to exclude the | symbol as an exception.
