Hello,
I have created a BRF+ function using the Delivered template application: CRMS4_SOM_PROD_CP_NUM_PARAM. The main idea is to get the values for contract start and end dates, calculate the duration of the contract and, using cross catalog mapping in Subscription product Specific data, populate a numeric field in the Charge Plan.
The function is working and returning the right value

And the configuration is done in SPRO

And the cross catalog mapping

However when i try to create a subscription contract i still get this error

Any Suggestions on how to solve this? To what may this be related?
Thank you!
